Configuring the NodeSync refresh data interval
Tune the configuration option if necessary to adjust the frequency of refreshing NodeSync status data in OpsCenter Monitoring.
address.yaml
The location of the address.yaml file depends on the type of installation:- Package installations: /var/lib/datastax-agent/conf/address.yaml
- Tarball installations: install_location/conf/address.yaml
cluster_name.conf
The location of the cluster_name.conf file depends on the type of installation:- Package installations: /etc/opscenter/clusters/cluster_name.conf
- Tarball installations: install_location/conf/clusters/cluster_name.conf
opscenterd.conf
The location of the opscenterd.conf file depends on the type of installation:- Package installations: /etc/opscenter/opscenterd.conf
- Tarball installations: install_location/conf/opscenterd.conf
Configuration option for NodeSync
The refresh period configuration option represents the period of time (in seconds)
between each NodeSync service refresh of status data from the NodeSync metrics
table. The default is 300 seconds (5 minutes). If a status refresh takes 2 minutes
to complete, the refresh period timer starts again and refreshes the NodeSync Status view after another 5 minutes.
- [nodesync] refresh_period
- The period of time in seconds between each NodeSync Service refresh of status data from the NodeSync metrics table. Default: 300 (5 mn).
Procedure
-
Open opscenterd.conf for all clusters, or
cluster_name.conf for a specific cluster.
If necessitated by your environment, open address.yaml for editing and configure at the node level. Do so for every node that requires a specific configuration override.
-
Set the following option for your environment requirements in the
[nodesync]section:The following configuration example triples the refresh interval from 5 minutes (300 seconds) to 15 minutes (900 seconds):[nodesync] refresh_period=900 - Restart opscenterd.
- Optional: If you made changes to address.yaml, restart the DataStax agents.
