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
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
OpsCenter can manage very large clusters up to 1000 nodes.
Note: Lifecycle Manager can
provision and manage up to 300 nodes per cluster within its UI. See How many nodes can Lifecycle Manager support when creating DataStax Enterprise clusters? for more
details.
When working with very large clusters, the performance of OpsCenter decreases with the default settings. To improve performance, adjust the cluster settings to increase the time period between polls of a cluster's nodes and token lists.
After adding a very large cluster to OpsCenter, change the following default settings:
