@ -36,70 +36,4 @@ Grafana is Loki's UI, so you'll also want to run one of those:
$ docker run -ti -p 3000:3000 -e "GF_EXPLORE_ENABLED=true" grafana/grafana:master
```
In the Grafana UI (http://localhost:3000), log in with "admin"/"admin", add a new "Grafana Logging" datasource for `http://host.docker.internal:3100`, then go to explore and enjoy!
## Usage Instructions
Loki is running in the ops-tools1 cluster. You can query logs from that cluster
using the following commands:
```
$ go get github.com/grafana/loki/cmd/logcli
$ . $GOPATH/src/github.com/grafana/loki/env # env vars inc. URL, username etc
$ logcli labels job
https://logs-dev-ops-tools1.grafana.net/api/prom/label/job/values
cortex-ops/consul
cortex-ops/cortex-gw
...
$ logcli query '{job="cortex-ops/consul"}'
https://logs-dev-ops-tools1.grafana.net/api/prom/query?query=%7Bjob%3D%22cortex-ops%2Fconsul%22%7D&limit=30&start=1529928228&end=1529931828&direction=backward&regexp=
Common labels: {job="cortex-ops/consul", namespace="cortex-ops"}
2018-06-25T12:52:09Z {instance="consul-8576459955-pl75w"} 2018/06/25 12:52:09 [INFO] raft: Snapshot to 475409 complete

```
The `logcli` command is temporary until we have Grafana integration. The URLs of
the requests are printed to help with integration work.

# Log CLI usage Instructions
Loki's main UI is Grafana; however, a basic CLI is provided as a proof of concept.
Once you have Loki running in a cluster, you can query logs from that cluster using the following commands:
```
$ go get github.com/grafana/loki/cmd/logcli
$ export GRAFANA_ADDR=https://logs-us-west1.grafana.net
$ export GRAFANA_USERNAME=<username>
$ export GRAFANA_PASSWORD=<password>
$ logcli labels job
https://logs-dev-ops-tools1.grafana.net/api/prom/label/job/values
cortex-ops/consul
cortex-ops/cortex-gw
...
$ logcli query '{job="cortex-ops/consul"}'
https://logs-dev-ops-tools1.grafana.net/api/prom/query?query=%7Bjob%3D%22cortex-ops%2Fconsul%22%7D&limit=30&start=1529928228&end=1529931828&direction=backward&regexp=
Common labels: {job="cortex-ops/consul", namespace="cortex-ops"}
2018-06-25T12:52:09Z {instance="consul-8576459955-pl75w"} 2018/06/25 12:52:09 [INFO] raft: Snapshot to 475409 complete
