InfluxDB system buckets contain time series data used by and generated from the
InfluxDB monitoring and alerting system and the task engine.
The following system buckets exist in each InfluxDB organization:
Each InfluxDB organization includes the following system buckets:
- [_monitoring](#_monitoring-system-bucket)
- [_tasks](#_tasks-system-bucket)
- [\_monitoring](#_monitoring-system-bucket)
- [\_tasks](#_tasks-system-bucket)
## _monitoring system bucket
The `_monitoring` system bucket stores data generated from and used by InfluxDB
[checks and notifications](/influxdb/v2.0/monitor-alert/).
{{% note %}}
The system bucket schemas below reference **InfluxDB data elements**.
