I have a couchbase installation in development (OSX, PHP libcouchbase, and Couchbase 2.01) which works without any issue but my production instance (Ubuntu, PHP libcouchbase, and Couchbase 2.1.1) is having a LOT of problems and I’m hoping I can get a little help on the following:
- Connections: even after restarting the machine I notice that the number of connections reported as being consistently around 80 connections. Keeping in mind that this site is not yet live and therefore has almost no usage, this seems abnormal or is it?
- CPU Spikes: the CPU seems to bounce between 40-60% on the Couchbase Console although running top from the command line indicates a somewhat lower utilisation. What is also pretty odd is that just watching the CPU meter chug along (again in the Couchbase Console) it seems to be popping up to 100% utilisation here and there and this is with zero load. Can anyone explain this?
- Page Faults:I am getting 0 "Major Faults" but my "Minor Faults" are constantly moving up and down between 1.5k to 5.5k. Again this is under zero load. Is this normal? Is there anywhere I can go to better understand what these variables actually mean?
