# LogCLI getting started

logcli is a command-line client for Loki that lets you run [LogQL](https://grafana.com/docs/loki/<LOKI_VERSION>/query) queries against your Loki instance. The `query` command will output extra information about the query and its results, such as the API URL, set of common labels, and set of excluded labels.

This is useful, for example, if you want to download a range of logs from Loki. Or want to perform analytical administration tasks, for example, discover the number of log streams to understand your label cardinality, or find out the estimated volume of data that a query will search over. You can also use logcli as part of shell scripts.

If you are a Grafana Cloud user, you can also use logcli to query logs that you have exported to long-term storage with [Cloud Logs Export](https://grafana.com/docs/grafana-cloud/send-data/logs/export/), or any other Loki formatted log data.

Note that logcli is a querying tool, it cannot be used to ingest logs.

## Install logcli

As a best practice, you should download the version of logcli that matches your Loki version. And upgrade your logcli when you upgrade your version of Loki.

### Binary (Recommended)

Download the `logcli` binary from the
[Loki releases page](https://github.com/grafana/loki/releases).

Builds are available for Linux, Mac, and Windows.

### Build LogCLI from source

Clone the Loki repository and build `logcli` from source:

```bash
git clone https://github.com/grafana/loki.git
cd loki
make logcli
```

Optionally, move the binary into a directory that is part of your `$PATH`.

```bash
cp cmd/logcli/logcli /usr/local/bin/logcli
```

## Set up command completion

You can set up tab-completion for `logcli` with one of the two options, depending on your shell:

- For bash, add this to your `~/.bashrc` file:

 ```bash
 eval "$(logcli --completion-script-bash)"
 ```

- For zsh, add this to your `~/.zshrc` file:

 ```bash
 eval "$(logcli --completion-script-zsh)"
 ```

## LogCLI usage

Once you have installed logcli, you can run it in the following way:

`logcli <command> [<flags>, <args> ...]`

`<command>` points to one of the commands, detailed in the [command reference](http://localhost:3002/docs/loki/<LOKI_VERSION>/query/logcli/getting-started/#logcli-command-reference) below.

`<flags>` is one of the subcommands available for each command.

`<args>` is a list of space separated arguments. Arguments can optionally be overridden using environment variables. Environment variables will always take precedence over command line arguments.

### Authenticate to Loki

To connect to a Loki instance, set the following argument:

- `--addr=http://loki.example.com:3100` or the `LOKI_ADDR` environment variable

For example, to query a local Loki instance directly without needing a username and password:

```bash
export LOKI_ADDR=http://localhost:3100

logcli query '{service_name="website"}'
```

To connect to a Loki instance which requires authentication, you will need to additionally set the following arguments:

- `--username` or the `LOKI_USERNAME` environment variable
- `--password` or the `LOKI_PASSWORD` environment variable

For example, to query Grafana Cloud:

```bash
export LOKI_ADDR=https://logs-us-west1.grafana.net
export LOKI_USERNAME=<username>
export LOKI_PASSWORD=<password>

logcli query '{service_name="website"}'
```

To specify a particular tenant, set the following argument:

- `--org-id` or the `LOKI_ORG_ID` environment variable

{{% admonition type="note" %}}
If you are running Loki behind a proxy server and you have
[authentication](https://grafana.com/docs/loki/<LOKI_VERSION>/operations/authentication/) configured, you will also have to pass in LOKI_USERNAME
and LOKI_PASSWORD, LOKI_BEARER_TOKEN or LOKI_BEARER_TOKEN_FILE accordingly.

                         bypassing an auth gateway.

Commands:
  help [<command>...]
    Show help.

  query [<flags>] <query>
    Run a LogQL query.

    The "query" command is useful for querying for logs. Logs can be returned in
    a few output modes:

      raw: log line
      default: log timestamp + log labels + log line
      jsonl: JSON response from Loki API of log line

    The output of the log can be specified with the "-o" flag, for example, "-o
    raw" for the raw output format.

    The "query" command will output extra information about the query and its
    results, such as the API URL, set of common labels, and set of excluded
    labels. This extra information can be suppressed with the --quiet flag.

    By default we look over the last hour of data; use --since to modify or
    provide specific start and end times with --from and --to respectively.

    Notice that when using --from and --to then ensure to use RFC3339Nano time
    format, but without timezone at the end. The local timezone will be added
    automatically or if using --timezone flag.

    Example:

      logcli query
         --timezone=UTC
         --from="2021-01-19T10:00:00Z"
         --to="2021-01-19T20:00:00Z"
         --output=jsonl
         'my-query'

    The output is limited to 30 entries by default; use --limit to increase.

    While "query" does support metrics queries, its output contains multiple
    data points between the start and end query time. This output is used to
    build graphs, similar to what is seen in the Grafana Explore graph view. If
    you are querying metrics and just want the most recent data point (like what
    is seen in the Grafana Explore table view), then you should use the
    "instant-query" command instead.

  instant-query [<flags>] <query>
    Run an instant LogQL query.

    The "instant-query" command is useful for evaluating a metric query for a
    single point in time. This is equivalent to the Grafana Explore table view;
    if you want a metrics query that is used to build a Grafana graph, you
    should use the "query" command instead.

    This command does not produce useful output when querying for log lines; you
    should always use the "query" command when you are running log queries.

    For more information about log queries and metric queries, refer to the
    LogQL documentation:

    https://grafana.com/docs/loki/<LOKI_VERSION>/logql/

  labels [<flags>] [<label>]
    Find values for a given label.

  series [<flags>] <matcher>
    Run series query.

    The "series" command will take the provided label matcher and return all the
    log streams found in the time window.

    It is possible to send an empty label matcher '{}' to return all streams.

    Use the --analyze-labels flag to get a summary of the labels found in all
    streams. This is helpful to find high cardinality labels.
```

### `query` command reference

The output of `logcli help query`:

```shell
usage: logcli query [<flags>] <query>

Run a LogQL query.

The "query" command is useful for querying for logs. Logs can be returned in a few output modes:

  raw: log line
  default: log timestamp + log labels + log line
  jsonl: JSON response from Loki API of log line

The output of the log can be specified with the "-o" flag, for example, "-o raw" for the raw output format.

The "query" command will output extra information about the query and its results, such as the API URL, set of common labels, and set of
excluded labels. This extra information can be suppressed with the --quiet flag.

By default we look over the last hour of data; use --since to modify or provide specific start and end times with --from and --to
respectively.

Notice that when using --from and --to then ensure to use RFC3339Nano time format, but without timezone at the end. The local timezone will be
added automatically or if using --timezone flag.

Example:

  logcli query
     --timezone=UTC
     --from="2021-01-19T10:00:00Z"
     --to="2021-01-19T20:00:00Z"
     --output=jsonl
     'my-query'

The output is limited to 30 entries by default; use --limit to increase.

While "query" does support metrics queries, its output contains multiple data points between the start and end query time. This output is used
to build graphs, similar to what is seen in the Grafana Explore graph view. If you are querying metrics and just want the most recent data
point (like what is seen in the Grafana Explore table view), then you should use the "instant-query" command instead.

Parallelization:

You can download an unlimited number of logs in parallel, there are a few flags which control this behavior:

  --parallel-duration
  --parallel-max-workers
  --part-path-prefix
  --overwrite-completed-parts
  --merge-parts
  --keep-parts

Refer to the help for each flag for details about what each of them do.

Example:

  logcli query
     --timezone=UTC
     --from="2021-01-19T10:00:00Z"
     --to="2021-01-19T20:00:00Z"
     --output=jsonl
     --parallel-duration="15m"
     --parallel-max-workers="4"
     --part-path-prefix="/tmp/my_query"
     --merge-parts
     'my-query'

This example will create a queue of jobs to execute, each being 15 minutes in duration. In this case, that means, for the 10-hour total
duration, there will be forty 15-minute jobs. The --limit flag is ignored.

It will start four workers, and they will each take a job to work on from the queue until all the jobs have been completed.

Each job will save a "part" file to the location specified by the --part-path-prefix. Different prefixes can be used to run multiple queries
at the same time. The timestamp of the start and end of the part is in the file name. While the part is being downloaded, the filename will
end in ".part", when it is complete, the file will be renamed to remove this ".part" extension. By default, if a completed part file is found,
that part will not be downloaded again. This can be overridden with the `--overwrite-completed-parts` flag.

Part file example using the previous command, adding --keep-parts so they are not deleted:

Since we don't have the --forward flag, the parts will be downloaded in reverse. Two of the workers have finished their jobs (last two files),
and have picked up the next jobs in the queue. Running ls, this is what we should expect to see.

$ ls -1 /tmp/my_query* /tmp/my_query_20210119T183000_20210119T184500.part.tmp /tmp/my_query_20210119T184500_20210119T190000.part.tmp
/tmp/my_query_20210119T190000_20210119T191500.part.tmp /tmp/my_query_20210119T191500_20210119T193000.part.tmp
/tmp/my_query_20210119T193000_20210119T194500.part /tmp/my_query_20210119T194500_20210119T200000.part

If you do not specify the `--merge-parts` flag, the part files will be downloaded, and logcli will exit, and you can process the files as you
wish. With the flag specified, the part files will be read in order, and the output printed to the terminal. The lines will be printed as
soon as the next part is complete, you don't have to wait for all the parts to download before getting output. The `--merge-parts` flag will
remove the part files when it is done reading each of them. To change this, you can use the `--keep-parts` flag, and the part files will not be
removed.

      --overwrite-completed-parts
                                Overwrites completed part files. This will download the range again, and replace the original completed part
                                file. Default will skip a range if it's part file is already downloaded.
      --merge-parts             Reads the part files in order and writes the output to stdout. Original part files will be deleted with this
                                option.
      --keep-parts              Overrides the default behavior of --merge-parts which will delete the part files once all the files have been
                                read. This option will keep the part files.
      --forward                 Scan forwards through logs.
      --no-labels               Do not print any labels
      --exclude-label=EXCLUDE-LABEL ...

      --include-label=INCLUDE-LABEL ...
                                Include labels given the provided key during output.
      --labels-length=0         Set a fixed padding to labels
      --store-config=""         Execute the current query using a configured storage from a given Loki configuration file.
      --remote-schema           Execute the current query using a remote schema retrieved from the configured -schema-store.
      --schema-store=""         Store used for retrieving remote schema.
      --colored-output          Show output with colored labels
  -t, --tail                    Tail the logs

### `instant-query` command reference

The output of `logcli help instant-query`:

```shell
usage: logcli instant-query [<flags>] <query>

Run an instant LogQL query.

The "instant-query" command is useful for evaluating a metric query for a single point in time. This is equivalent to the Grafana Explore
table view; if you want a metrics query that is used to build a Grafana graph, you should use the "query" command instead.

This command does not produce useful output when querying for log lines; you should always use the "query" command when you are running log
queries.

For more information about log queries and metric queries, refer to the LogQL documentation:

### `volume_range` command reference

The output of `logcli help volume_range`:

```shell
usage: logcli volume_range [<flags>] <query>

Run a volume query and return timeseries data.

The "volume_range" command will take the provided label selector(s) and return aggregate volumes for series matching those volumes, aggregated
into buckets according to the step value. This only works against Loki instances using the TSDB index format.

By default we look over the last hour of data; use --since to modify or provide specific start and end times with --from and --to
respectively.

Notice that when using --from and --to then ensure to use RFC3339Nano time format, but without timezone at the end. The local timezone will be
added automatically or if using --timezone flag.

Example:

        logcli volume_range

### Use `--stdin` to query locally

You can use the logcli `–stdin` argument to run a command against a log file on your local machine, instead of a Loki instance. This lets you use LogQL to query a local log file without having to load the file into Loki, for example if you have downloaded a log file and want to query it outside of Loki.

If you have log files in your local machine, and just want to run some LogQL queries against those log files, `--stdin` flag can help.

You may use `stdin` flag to do the following:

- Use as a quick way to test or validate a LogQL expression against some log data.
- Learn the basics of LogQL with just local log files and the `logcli` tool (without needing to set up Loki servers, Grafana, etc.).
- Enable troubleshooting by letting you run queries without accessing a Loki instance.
- Use LogQL to parse and extract data from a local log file without ingesting the data into Loki.
- Enable discussion on public forums, for example submitting questions and answers, and sharing LogQL expressions.

#### Notes on `stdin` usage

1. The `--limits` flag doesn't have any meaning when using `--stdin` (use pager like `less` for that).
1. Be aware there are no **labels** when using `--stdin`. So the stream selector in the query is optional, for example, just `|="timeout"|logfmt|level="error"` is same as `{foo="bar"}|="timeout|logfmt|level="error"`.

{{< admonition type="note" >}}
Currently `stdin` doesn't support any type of metric queries.
{{< /admonition >}}

#### `stdin` examples

- Line filter - `cat mylog.log | logcli --stdin query '|="too many open connections"'`
- Label matcher - `echo 'msg="timeout happened" level="warning"' | logcli --stdin query '|logfmt|level="warning"'`
- Different parsers (logfmt, json, pattern, regexp) - `cat mylog.log | logcli --stdin query '|pattern <ip> - - <_> "<method> <uri> <_>" <status> <size> <_> "<agent>" <_>'`
- Line formatters - `cat mylog.log | logcli --stdin query '|logfmt|line_format "{{.query}} {{.duration}}"'`

## Batching

logcli sends queries to Loki in such a way that query results arrive in batches.

The `--limit` option for a `logcli query` command limits the total number of log lines that will be returned for a single query.
When not set, `--limit` defaults to 30.
The limit protects the user from overwhelming Loki in cases where the specified query would have returned a large number of log lines.
The limit also protects the user from unexpectedly large responses.

Larger result sets can be batched for easier consumption. Use the `--batch` option to control the number of log line results that are returned in each batch.
When not set, `--batch` defaults to 1000.

Setting a `--limit` value larger than the `--batch` value will cause the
requests from logcli to Loki to be batched.

When you run a query in Loki, it will return up to a certain number of log lines. By default, this limit is 5000 lines. You can configure this server limit with the `limits_config.max_entries_limit_per_query` in Loki's configuration.

Batching lets you query for a results set that is larger than this server-side limit, as long as the `--batch` value is less than the server limit.

Query metadata is output to `stderr` for each batch.
To suppress the output of the query metadata, set the `--quiet` option on the `logcli query` command line.

## logcli example queries

Here are some examples of logcli.

Find all values for a label.

```bash
logcli labels job
```

```bash
https://logs-dev-ops-tools1.grafana.net/api/prom/label/job/values
loki-ops/consul
loki-ops/loki-gw
```

Print all labels and their unique values. This command is especially useful for finding [high-cardinality labels](https://grafana.com/docs/loki/<LOKI_VERSION>/get-started/labels/#cardinality) in the index.

```bash
logcli series '{cluster="vinson"}' --analyze-labels
```

```bash
2024/10/31 13:46:25 https://logs-prod-008.grafana.net/loki/api/v1/series?end=1730382385746344416&match=%7Bcluster%3D%22vinson%22%7D&start=1730378785746344416
Total Streams:  10
Unique Labels:  10

Label Name       Unique Values  Found In Streams
service_name        8          10

instance            1          3
cluster             1          10
```

Get all logs for a given stream

```bash
logcli query '{job="loki-ops/consul"}'
```

```bash
https://logs-dev-ops-tools1.grafana.net/api/prom/query?query=%7Bjob%3D%22loki-ops%2Fconsul%22%7D&limit=30&start=1529928228&end=1529931828&direction=backward&regexp=
Common labels: {job="loki-ops/consul", namespace="loki-ops"}
2018-06-25T12:52:09Z {instance="consul-8576459955-pl75w"} 2018/06/25 12:52:09 [INFO] raft: Snapshot to 475409 complete

```

Print all log streams for the given stream selector. This example shows all known label combinations that match your query.

```bash
logcli series -q --match='{namespace="loki",container_name="loki"}'
```

```bash
{app="loki", container_name="loki", controller_revision_hash="loki-57c9df47f4", filename="/var/log/pods/loki_loki-0_8ed03ded-bacb-4b13-a6fe-53a445a15887/loki/0.log", instance="loki-0", job="loki/loki", name="loki", namespace="loki", release="loki", statefulset_kubernetes_io_pod_name="loki-0", stream="stderr"}
```

## Troubleshoot logcli

Make sure that the version of Logcli you are using matches your Loki version.
You can check your logcli version with the following command:

```bash
logcli –version
```

If you experience timeouts, you can update the following setting in your `logcli-config.yaml` file.

```yaml
limits_config:
  query_timeout: 10m
```
