High cpu usage on server

[deanpm70]

Hi Matt,

Took me a while to get around to this but as per our conversation on reddit, I was seeing viewu burning a lot of cpu cycles. Output from docker status viewu;

CONTAINER ID   NAME      CPU %     MEM USAGE / LIMIT    MEM %     NET I/O       BLOCK I/O    PIDS
33395d1d3430   viewu     117.18%   6.77MiB / 15.56GiB   0.04%     4.48kB / 0B   344kB / 0B   10

The number is hovering around the 118 mark. Output from viewu logs is revealing and might explain the behaviour;

CERROR::ConnectionError::I/O: Connection refused (os error 111)
CERROR::ConnectionError::I/O: Connection refused (os error 111)
CERROR::ConnectionError::I/O: Connection refused (os error 111)
CERROR::ConnectionError::I/O: Connection refused (os error 111)

This error is repeated a LOT. I'm still waiting for an export of the log to count the entries but the log file is at 2GB so far and growing about 100MB every couple of seconds. There are 73 million entries so far so I'm going to abort the export and start looking at config but for now, I think we can safely assume that this is at least a contributing factor to the high cpu usage :)

And.... I think I've found the culprit. I had specified the connection to the mqtt server as 127.0.0.1 but for "reasons", I must have configured mqtt to only listen on it's external interface. Having made the change, viewu isn't even registering in terms of cpu usage.

Nice. I’m glad you found the issue. Is there anything I need to do or can this be marked as answered? That’s a huge log file!

I think we can close it as answered 😁DeanOn 23 May 2024, at 20:33, mjehrhart ***@***.***> wrote: Nice. I’m glad you found the issue. Is there anything I need to do or can this be marked as answered?
