Question & Answer
Question
Does RTM have a graph which contains total available memory of the cluster?
Answer
There is no graph graph that shows the total available memory for all the hosts for a cluster.
The graph name "<Cluster_Name>_Summary - Grid Available Memory" does not show up the total available memory for the cluster.
Go to Graphs tab-> Cluster-cluster name->Grid available memory.
- The graph "<Cluster_name>_Summary - Grid Available Memory" doesn't show the total available memory. It shows the total average available memory of all the hosts. The confusion occurs due to its name. So the graph is about total average memory, minimum average and max average memory of all the hosts.
- Its coming from the below sql query.
The total available memory of the cluster can be calculated by the below sql query:
# mysql cacti -e "SELECT sum(mem) as a_mem, sum(swp) as a_swp FROM grid_load WHERE (status NOT LIKE 'U%') AND clusterid = 1 GROUP BY clusterid;"
(Note: please change the cluster id to your cluster id number)
