httpd.pointsWrittenDropped in _internal

Hi guys !

I’m trying to understand all metric available in the _internal database.
I’ve found some documentation here (outdated) and of course here but I still have some questions.

For example, do you know the difference between httpd.pointsWrittenDropped and httpd.pointsWrittendFail ?

I’m looking for detailed documentation on these metrics for quite a long time now but have not found anything. Some help would be very appreciable!

Thank you,

Bastien

Hi guys !

No idea difference between both metrics ?

I am also wondering what tsm1_cache.cachedBytes, tsm1_cache.diskBytes and tsm1_cache.memBytes corresponds to ?

As far as I understand how InfluxDB works, InfluxDB cache is only located in memory so I don’t understand why there is a tsm1_cache.diskBytes metric.

Does tsm1_cache.cachedBytes and tsm1_cache.memBytes respectively corresponds to amount of cache memory used by InfluxDB and amount of “classic” (in the sense not buffer memory, not cache memory) memory used by Influx processes ?

Thank you,

Hello, any update on this? I am trying to monitor the performance of my server. I see the cached bytes continuously increasing. I’ve had the system running for 3 days and I have 6.5GiB of cashed bytes. Does this mean that the server receiving more fields than it can handle?
