Optional basic auth password for -datasource.url
-datasource.basicAuth.username string
Optional basic auth username for -datasource.url
-datasource.lookback duration
-datasource.lookback duration
Lookback defines how far to look into past when evaluating queries. For example, if datasource.lookback=5m then param "time" with value now()-5m will be added to every query.
-datasource.maxIdleConnections int
Defines the number of idle (keep-alive connections) to configured datasource.Consider to set this value equal to the value: groups_total * group.concurrency. Too low value may result into high number of sockets in TIME_WAIT state. (default 100)
-datasource.tlsCAFile string
Optional path to TLS CA file to use for verifying connections to -datasource.url. By default system CA is used
-datasource.tlsCertFile string

has at least 20% of free space comparing to disk size. The remaining amount of free space
can be [monitored](#monitoring) via `vm_free_disk_space_bytes` metric. The total size of data
stored on the disk can be monitored via sum of `vm_data_size_bytes` metrics.
See also `vm_merge_need_free_disk_space` metrics, which are set to 1 if background merge cannot be initiated due to free disk space shortage.
See also `vm_merge_need_free_disk_space` metrics, which are set to values higher than 0
if background merge cannot be initiated due to free disk space shortage. The value shows the number of per-month partitions,
which would start background merge if they had more free disk space.
* If VictoriaMetrics doesn't work because of certain parts are corrupted due to disk errors,
then just remove directories with broken parts. This will recover VictoriaMetrics at the cost
