Threshold alerts for Tendrl objects #154

Closed r0h4n closed 7 years ago

r0h4n commented 7 years ago

Currently I am not sure if tendrl-alerting provides ability to get alerts on any object based on a custom threshold, This is required for users to be able to set custom thresholds on Tendrl objects and receive alerts for the same

@anmolbabu please provide inputs on this

@r0h4n Yes we need the ability to look at a config file for the various objects and alert based on that custom threshold. For example in some cases Ceph admins do not think that having 75% free space in their pool is enough and they want to make this lower. So there is a need for cluster thresholds and node thresholds that are configurable. I think the node thresholds should be a setting that applies cluster wide within a given set of cluster nodes by node type. For example all OSDs in a cluster. Having each and every node with it's own threshold is too much trouble and is overkill imo.
