Critical CDVR Log Alerts via E-Mail

Thank you! My logs don't show a restart, but I tried your path, and that seems to have worked. I'm going in now and playing around with things. (OliveTin seems to be working, as I was able to use it just now to restart the server)

It's correct if you're running Channels DVR on a Synology using the Synology package.

You can view the logs going back further by specifying the number of lines you want to view
http://x.x.x.x:8089/log?n=10000
where x.x.x.x is the IP address of your Channels DVR Server and n=10000 is the number of lines to display

Try:

/Users/<your_username>/Library/Application Support/ChannelsDVR

It's OK, but unnecessary, just don't define that value in the env vars section.

What is this error ? ... Google email works but I see this error ... In container Log.

level="info" msg="UserFromContext" usergroup="" username=""
level="info" msg="UserFromContext" usergroup="" username=""
level="info" msg="UserFromContext" usergroup="" username=""

Not actually an error, just an info message. These can be ignored.

Run the OliveTin Post-Install Healthcheck Action and post the results here, and we'll see where you're at. Sensitive info is automatically redacted.

Here it is (I didn't run the extended check, because it told me to run a sudo command from the directory I have bound to /config, but I don't know what that directory would be):

Oh, and after using OliveTin to restart Channels, my variable for LOGS_SHARE is /Users/myname/Library/Application Support/ChannelsDVR/data

Should I be taking the "data" off the end?

Yes.

No problem, basic check is fine at this point. Everything other than removing "data" from your LOGS_SHARE path looks good. Congrats you're OliveTinning!

Went through all six of my DVR's logs and updated the lists in this post Critical CDVR Log Alerts via E-Mail - #19 by chDVRuser

Looks like [ERR] filter would cover all those.

That gives a lot of unnecessary noise.
From one of my servers

[ERR] Could not find series
[ERR] Could not probe file
[ERR] Could not start stream
[ERR] Error during stream
[ERR] Failed to clean up
[ERR] Failed to download XMLTV
[ERR] Failed to fetch guide providers:

[ERR] Probe failed for live stream
[ERR] Scanner error walking /shares/dvr/Imports/Videos: open .: too many open files
[ERR] ULK failure:
[ERR] ULK invalid:
[ERR] ULK response:

They all seem important. That is how I just set it up will see if my phone goes crazy but I very seldom get any of those errors... but in your case you probably want to set each one separately.

That's excellent -- thank you!

More filter fields might be a good start. Maybe 20?

I have them as grep files in OliveTin
dvrcritical.grep

recfailed.grep

I don't consider these guide fetch errors "critical", but I have a cron job checking for these once a day.

Loving the new OliveTin E-Mail Log Alerts Action! Had this e-mail first thing this morning, which reminded me I needed to make a few changes to my Sunday passes -- and as result, got several recordings I would have otherwise missed:

screencapture-file-C-Users-slayer-Downloads-screenshot-mail-google-com-2024-05-05-14-26-24-png-2024-05-05-14_31_35-edit

I'm unable to get this running and get an error message.

Here is my healthcheck run. Sorry, I can't figure this out. :slightly_frowning_face:

No problem. It looks like your LOGS_SHARE value isn't correct atm. This is on Synology correct? What's the full path to your CDVR executable, starting with /volume1? You should be able to use the Synology file explorer to find the correct directory.

For LOGS_SHARE, when you see directories like data, latest and a number of them with dates -- that's the parent dir value to use.

EDIT: You're currently using the path that includes the logs directory in with your recordings. LOGS_SHARE needs the path to where the CDVR executable is located:
