Configuring for very large clusters
OpsCenter can manage clusters containing multiple hundreds of nodes. When managing very large clusters with up to 1000 nodes, adjusting cluster configuration settings improves performance.
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
- Windows installations: Program Files (x86)\DataStax Community\opscenter\conf\clusters\cluster_name.conf
OpsCenter can manage very large clusters up to 1000 nodes. When working with very large clusters, the performance of OpsCenter decreases with the default settings. To improve performance, adjust the cluster settings to turn off automatic node discovery and increase the time period between polls of a cluster's nodes and token lists.
After a very large cluster has been added to OpsCenter, change the following settings in the cluster_name.conf.
