Configuring for very large clusters
OpsCenter can manage clusters containing multiple hundreds of nodes. Use the following settings when managing very large clusters with up to 1000 nodes.
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
The performance of OpsCenter decreases with the default settings when working with very large clusters. 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.
Once a very large cluster has been added to OpsCenter, change the following settings in the cluster_name.conf.
