## Victoria Metrics Cluster Per Tenant Statistic
|
||||
|
||||
<img alt="cluster-per-tenant-stat" src="per-tenant-stats.jpg">
|
||||
|
||||
Enterprise version of Victoria Metrics Cluster exposes usage statistic for each tenant.
|
||||
|
||||
The next statistic is exposed:
|
||||
|
||||
- `vminsert`
|
||||
|
||||
* `vm_tenant_inserted_rows_total` - the ingestion rate by tenant
|
||||
- `vmselect`
|
||||
|
||||
* `vm_tenant_select_requests_duration_ms_total` - query latency by tenant. It can be usefull for identifing tenant with the most heaviest queries
|
||||
* `vm_tenant_select_requests_total` - total requests. You can calculate request rate (qps) by using this metric
|
||||
|
||||
- `vmstorage`
|
||||
* `vm_tenant_active_timeseries` - the number of active timeseries
|
||||
* `vm_tenant_used_tenant_bytes` - the disk spaces is consumed by metrics for particular tenant
|
||||
* `vm_tenant_timeseries_created_total` - the total number for timeseries by tenant
|
||||
|
||||
|
||||
The information should be scrapped by the agent (`vmagent`, `victoriametrics`, prometheus, etc) and stored in TSDB. This can be the same cluster but a different tenant, but we encourage to use one more instance of TSDB (more lightweight, eg. VM single) for monitoring of monitoring.
|
||||
|
||||
the config example for statistic scrapping
|
||||
|
||||
```yaml
|
||||
scrape_configs:
|
||||
- job_name: cluster
|
||||
scrape_interval: 10s
|
||||
static_configs:
|
||||
- targets: ['vmselect:8481','vmstorage:8482','vminsert:8480']
|
||||
```
|
||||
|
||||
### Visualization
|
||||
|
||||
Visualisation of statistic can be done in grafana using this dashboard [link](https://github.com/VictoriaMetrics/VictoriaMetrics/tree/cluster/dashboards/clusterbytenant.json)
|
||||
|
||||
|
||||
### Integration with vmgateway:
|
||||
|
||||
Per Tenant Statistic is the source data for `vmgateway` rate limiter. More information can be found [here](https://victoriametrics.github.io/vmgateway.html)
|
||||
|
||||
### Integration with vmalert:
|
||||
|
||||
You can generate alerts based on each tenant resource usage and notify the system/people about reaching the limits.
|
||||
|
||||
here is an example of alert by high churn rate by the tenant
|
||||
|
||||
```yaml
|
||||
|
||||
- alert: TooHighChurnRate
|
||||
expr: |
|
||||
(
|
||||
sum(rate(vm_tenant_timeseries_created_total[5m])) by(accountID,projectID)
|
||||
/
|
||||
sum(rate(vm_tenant_inserted_rows_total[5m])) by(accountID,projectID)
|
||||
) > 0.1
|
||||
for: 15m
|
||||
labels:
|
||||
severity: warning
|
||||
annotations:
|
||||
summary: "Churn rate is more than 10% for the last 15m"
|
||||
description: "VM constantly creates new time series at tenant: {{ $labels.accountID }}:{{ $labels.projectID }}.\n
|
||||
This effect is known as Churn Rate.\n
|
||||
High Churn Rate tightly connected with database performance and may
|
||||
result in unexpected OOM's or slow queries."

||||
