This reverts commit 3d7a77bf82.
Reason for revert: relative links do not work properly at GitHub code
and at GitHub wiki. For example, the following page contains broken links
before reverting this commit:
https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/docs/VictoriaLogs/CHANGELOG.md
It is always better to use absolute links thank relative links, since the page contents
can be copy-n-pasted to other pages, which are located in vastly different directories,
and all the links will remain working.

# Promtail setup
|
|
|
|
[Promtail](https://grafana.com/docs/loki/latest/clients/promtail/) is a default log shipper for Grafana Loki.
|
|
Promtail can be configured to send the collected logs to VictoriaLogs according to the following docs.
|
|
|
|
Specify [`clients`](https://grafana.com/docs/loki/latest/clients/promtail/configuration/#clients) section in the configuration file
|
|
for sending the collected logs to [VictoriaLogs](https://docs.victoriametrics.com/VictoriaLogs/):
|
|
|
|
```yaml
|
|
clients:
|
|
- url: http://localhost:9428/insert/loki/api/v1/push?_stream_fields=instance,job,host,app
|
|
```
|
|
|
|
Substitute `localhost:9428` address inside `clients` with the real TCP address of VictoriaLogs.
|
|
|
|
By default VictoriaLogs stores all the ingested logs into a single [log stream](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html#stream-fields).
|
|
Storing all the logs in a single log stream may be not so efficient, so it is recommended to specify `_stream_fields` query arg
|
|
with the list of labels, which uniquely identify log streams. There is no need in specifying all the labels Promtail generates there -
|
|
it is usually enough specifying `instance` and `job` labels. See [these docs](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html#stream-fields)
|
|
for details.
|
|
|
|
See also [these docs](https://docs.victoriametrics.com/VictoriaLogs/data-ingestion/#http-parameters) for details on other supported query args.
|
|
There is no need in specifying `_msg_field` and `_time_field` query args, since VictoriaLogs automatically extracts log message and timestamp from the ingested Loki data.
|
|
|
|
It is recommended verifying whether the initial setup generates the needed [log fields](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html#data-model)
|
|
and uses the correct [stream fields](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html#stream-fields).
|
|
This can be done by specifying `debug` [parameter](https://docs.victoriametrics.com/VictoriaLogs/data-ingestion/#http-parameters)
|
|
and inspecting VictoriaLogs logs then:
|
|
|
|
```yaml
|
|
clients:
|
|
- url: http://localhost:9428/insert/loki/api/v1/push?_stream_fields=instance,job,host,app&debug=1
|
|
```
|
|
|
|
If some [log fields](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html#data-model) must be skipped
|
|
during data ingestion, then they can be put into `ignore_fields` [parameter](https://docs.victoriametrics.com/VictoriaLogs/data-ingestion/#http-parameters).
|
|
For example, the following config instructs VictoriaLogs to ignore `filename` and `stream` fields in the ingested logs:
|
|
|
|
```yaml
|
|
clients:
|
|
- url: http://localhost:9428/insert/loki/api/v1/push?_stream_fields=instance,job,host,app&ignore_fields=filename,stream
|
|
```
|
|
|
|
By default the ingested logs are stored in the `(AccountID=0, ProjectID=0)` [tenant](https://docs.victoriametrics.com/VictoriaLogs/#multitenancy).
|
|
If you need storing logs in other tenant, then specify the needed tenant via `tenant_id` field
|
|
in the [Loki client configuration](https://grafana.com/docs/loki/latest/clients/promtail/configuration/#clients)
|
|
The `tenant_id` must have `AccountID:ProjectID` format, where `AccountID` and `ProjectID` are arbitrary uint32 numbers.
|
|
For example, the following config instructs VictoriaLogs to store logs in the `(AccountID=12, ProjectID=34)` [tenant](https://docs.victoriametrics.com/VictoriaLogs/#multitenancy):
|
|
|
|
```yaml
|
|
clients:
|
|
- url: http://localhost:9428/insert/loki/api/v1/push?_stream_fields=instance,job,host,app&debug=1
|
|
tenant_id: "12:34"
|
|
```
|
|
|
|
The ingested log entries can be queried according to [these docs](https://docs.victoriametrics.com/VictoriaLogs/querying/).
