Couchbase nodes Standalone Heartbeat time

I know counchbase nodes do heartbeat/watchdog to detect their status is up/running. But want to know what is the periodic time of heartbeat and howmany heartbeat should fail before couchbase management server shows the node as a Down. Also is there any way to change that periodic time or count.

I don’t believe this question was ever answered. We’re seeing some of our servers occasionally going into pending mode (for about 30 seconds) which would indicate a heartbeat was missed. I haven’t found any information on how this could be monitored externally or how to trouble shoot this.

If anyone knows how to monitor this that would be greatly appreciated.
