Hello,
I am working on setting up a monitoring tool to monitor Cassandra Instances. Are there any wikis which specifies optimum value for each Cassandra KPIs? For instance, I am not sure, What value of "Memtable Columns Count" can be considered as "Normal". What value of the same has to be considered as "Critical". I knew threshold numbers for few params, for instance any thing more than zero for timeouts, pending tasks should be considered as unusual. Also, I am aware that most of the statistics' threshold numbers vary in accordance with Hardware Specification, Cassandra Environment Setup. But, what I request here is a general guideline for configuring thresholds for all the metrics. If this has been already covered, please point me to that resource. If anyone on their own interest collected these things, please share. Any help is appreciated. Best Regards, Julian.
