Tendrl objects should sync (from sds/node) independently at custom intervals #153

Closed r0h4n closed 7 years ago

r0h4n commented 7 years ago

Currently, Tendrl objects (node.network, node.cpu, sds objects like pool, volumes etc) sync at a global fixed interval

Required: Tendrl objects should sync at custom intervals per object based on their own sync intervals and priorities.

Why: This allows users to have more frequent updates/alerts to critical objects

japplewhite commented 7 years ago

The real intent here is to have Tendrl alert more quickly than 5 minutes for critical storage events like node down, failed disk, OSD down/out/missing, brick down, volume down/degraded. Other issues can sync on the regular update. I don't want to gold plate this though. If we could at least have a way to prioritize node and disk failures that would suffice.

OSDs, brick, volume: sync at at a 3 second interval to central store cc: @anmolbabu whats the threshold alert update interval and are there intervals monitoring statuses of all of these objects

Node and Disk inventory: Updated every 8 seconds. cc: @anmolbabu do you have alerts in place for failed disks, nodes ?
