`vlogsqcli` is an interactive command-line tool for querying [VictoriaLogs](https://docs.victoriametrics.com/victorialogs/).
|
|
This tool can be obtained from the linked release pages at the [changelog](https://docs.victoriametrics.com/victorialogs/changelog/)
|
|
or from [docker images](https://hub.docker.com/r/victoriametrics/vlogscli/tags).
|
|
|
|
By default `vlogscli` sends queries to [`http://localhost:8429/select/logsql/query`](https://docs.victoriametrics.com/victorialogs/querying/#querying-logs).
|
|
The url to query can be changed via `-datasource.url` command-line flag. For example, the following command instructs
|
|
`vlogsql` sending queries to `https://victoria-logs.some-domain.com/select/logsql/query`:
|
|
|
|
```sh
|
|
./vlogsql -datasource.url='https://victoria-logs.some-domain.com/select/logsql/query'
|
|
```
|
|
|
|
If some HTTP request headers must be passed to the querying API, then set `-header` command-line flag.
|
|
For example, the following command starts `vlogsql`,
|
|
which queries `(AccountID=123, ProjectID=456)` [tenant](https://docs.victoriametrics.com/victorialogs/#multitenancy):
|
|
|
|
```sh
|
|
./vlogsql -header='AccountID: 123' -header='ProjectID: 456'
|
|
```
|
|
|
|
After the start `vlogsql` provides a prompt for writing [LogsQL](https://docs.victoriametrics.com/victorialogs/logsql/) queries.
|
|
The query can be multi-line. The is sent to VictoriaLogs as soon as it contains `;` at the end or if a blank line follows the query.
|
|
For example:
|
|
|
|
```sh
|
|
;> _time:1y | count();
|
|
executing [_time:1y | stats count(*) as "count(*)"]...
|
|
{
|
|
"count(*)": "1923019991"
|
|
}
|
|
duration: 0.688s
|
|
```
|
|
|
|
Query execution can be interrupted at any time by pressing `Ctrl+C`.
|
|
|
|
Type `q`, `quit` or `exit` and the press `Enter` for exit from `vlogsql`.
|
|
|
|
If the query response exceeds vertical screen space, the `vlogsql` pipes query response to `less` utility,
|
|
so you can scroll the response as needed. This allows executing queries, which potentially
|
|
may return billions of rows, without any problems at both VictoriaMetrics and `vlogsql` sides,
|
|
thanks to the way how `less` interacts with [`/select/logsql/query`](https://docs.victoriametrics.com/victorialogs/querying/#querying-logs):
|
|
|
|
- `less` reads the response when needed, e.g. when you scroll it down.
|
|
`less` pauses reading the response when you stop scrolling. VictoriaLogs pauses processing the query
|
|
when `less` stops reading the response, and automatically resumes processing the response
|
|
when `less` continues reading it.
|
|
- `less` closes the response stream after exit from scroll mode (e.g. by typing `q`).
|
|
VictoriaLogs stops query processing and frees up all the associated resources
|
|
after the response stream is closed.
|
|
|
|

## Query history
|
|
|
|
`vlogsql` supports query history - press `up` and `down` keys for navigating the history.
|
|
By default the history is stored in the `vlogsql-history` file at the directory where `vlogsql` runs,
|
|
so the history is available between `vlogsql` runs.
|
|
The path to the file can be changed via `-historyFile` command-line flag.
|
|
|
|
Quick tip: type some text and then press `Ctrl+R` for searching queries with the given text in the history.
|
|
Press `Ctrl+R` multiple times for searching other matching queries in the history.
|
|
Press `Enter` when the needed query is found in order to execute it.
|
|
Press `Ctrl+C` for exit from the `search history` mode.
