Hi Anton, Thanks for brining this out!
The memory metrics really need a serious overhaul. For instance we a missing basic things like: - Bytes used per data region. - Bytes used per cache. - Size of checkpointing buffer. Plus advanced memory metrics will not be harmful: - Space occupied by indexes. The ticket for the memory metrics improved is anxiously waiting to be solved: https://issues.apache.org/jira/browse/IGNITE-5796 <https://issues.apache.org/jira/browse/IGNITE-5796> — Denis > On Nov 13, 2017, at 9:14 AM, Anton Vinogradov <[email protected]> wrote: > > Igniters, > > As you may know Ignite have a lot of JMX based metric, but to perform more > effective grid monitoring some new JMX metrics needs to be implemented. > > Here's the accumulated list of metrics I'd like to see at nearest Ignite > version: > Topology > - Current topology version > - Total server nodes count > - Total client nodes count > - Method to count nodes filtered by some node attribute > - Method to count nodes grouped by some node attribute > > Communication SPI > - Received messages count grouped by message type > - Received messages count grouped by sender node > - Sent messages count grouped by message type > - Sent messages count grouped by receiver node > > Partitions allocation (for cache groups) > - Total primary partitions count located on the current node > - Total backup partitions count located on the current node > - Min/max partition backups left in the cluster for cache group > - Maybe some methods to show partitions map/partition distribution > statistics in the cluster > > Jobs execution > - Total jobs execution time (now job execution statistics gathered since > node started and can't be used to calculate average execution time between > probes, implementation of this metric can solve this problem) > > Cache > - Topology validation status for cache > > IEP-6 [1] was prepared and ready to be discussed. > > Please, feel free to suggect or decline some metric. > > Anton. > > [1] > https://cwiki.apache.org/confluence/display/IGNITE/IEP-6%3A+Metrics+improvements
