Monitoring Delta Synchronization

Heavily loaded clusters and clusters with geographically separated members pose special challenges. High connection rates, and large distances between the members can lead to delays that affect the operation of the cluster.

Monitor the operation of the State Synchronization mechanism in highly loaded and distributed clusters.

Perform these troubleshooting steps:

1. Shows the Delta Sync statistics counters:

   Shell	Command
   Gaia Clish	show cluster statistics sync
   Expert mode	cphaprob syncstat

2. Examine and understand the Delta Sync statistics.
3. Tune the relevant synchronization global configuration parameters.
4. Reset the Delta Sync statistics counters:

   Shell	Command
   Gaia Clish	show cluster statistics sync reset
   Expert mode	cphaprob -reset syncstat

5. Examine the Delta Sync statistics to see if the problem is solved.
6. Solve any identified problem.
