3.13 Update the InfluxDB Data Retention Policy
Prerequisites
This procedure requires root privileges. Before performing this procedure, use the
urika-state
command to
ensure that the system is operating in the service mode that supports using InfluxDB. For more information, see
the
urika-state
man page and refer to
on page 177.
About this task
The data retention policy for InfluxDB defaults to infinite, i.e. data is never deleted. As a result, Spark and Hadoop
Grafana dashboards may take longer to load and InfluxDB may take up more space than necessary. To reduce
the amount of space being used by InfluxDB, the data retention policy for each database needs to be reduced, as
described in this procedure. Reducing the data retention policy for Spark and Hadoop databases can reduce the
load time of the Spark and Hadoop Grafana dashboards.
Procedure
1. Log on to login2 and become root.
2. Switch to the
/var/lib/influxdb/data
directory.
#
cd /var/lib/influxdb/data
3. Use the
du
command to show how much space being used.
