Validate error after performance tuning

[Fire-IT_Tech_Channel]

Good day

Seems like after making some performance changes i followed this link.
https://docs.librenms.org/Support/Performance/

I get this error anyone else with this error.
/opt/librenms# ./validate.php

Any help will be greatly appreciated if someone can assist me.

I wonder if you had that error before performance tuning?

Post output of
./scripts/composer_wrapper.php install --no-dev

[Fire-IT_Tech_Channel]

Ok I have run this command the output is.

./scripts/composer_wrapper.php install --no-dev

It seems that class was added recently, @murrant may know

[murrant]

Does that file exist? app\Console\Commands\BashCompletionCommand.php

Probably just something messed up in your install. Run git status and report the output.

HI Murrant

fatal: not a git repository (or any of the parent directories): .git

and it does look like this does not exist app\Console\Commands\BashCompletionCommand.php

[Chas]

so you were in your install directory (default /opt/librenms) and you ran git status, and it said fatal: not a git repository ?

How did you install it?

[Fire-IT_Tech_Channel]

Hi Chas

Ok seems like i have been bit of idiot here, after running the git status in the ocrrect directory found few other things here.

Your branch is behind ‘origin/master’ by 79 commits, and can be fast-forwarded.
(use “git pull” to update your local branch)

i then ran git pull (in the correct directory which gave me this)
Updating 5197074c4…2eac72d34
error: Your local changes to the following files would be overwritten by merge:
LibreNMS/Util/GitHub.php
LibreNMS/Util/Version.php
app/Console/Kernel.php
app/Http/Controllers/Table/DeviceController.php
app/Models/Device.php
doc/General/Changelog.md
includes/common.php
storage/debugbar/.gitignore
storage/framework/cache/.gitignore
Please commit your changes or stash them before you merge.

I decided to run then ./scripts/github-remove -d
then I ran ./daily.sh

Which came back with
Re-running /opt/librenms/daily.sh as librenms user
Updating to latest codebase OK
Updating Composer packages OK
Updated from 5197074c4 to 2eac72d34 OK
Updating SQL-Schema OK
Updating submodules OK
Cleaning up DB OK
Fetching notifications OK
Caching PeeringDB data OK

However seems like some of the performance changes I made definitely had an impact.
Cause if i run

./validate.php

So thanks for the help just need to figure out the performance thing.

[Fire-IT_Tech_Channel]

Any advice again will be appreciated seriously thank you so far.

[Chas]

Good that you got past that error,

What information can you gather from the Settings → Pollers section ?

How many devices are affected, latency to those devices, did you try turning off polling modules to those devices.

[Fire-IT_Tech_Channel]

this is the other thing this web page is so slow, i need to keep refreshing pages to get it to display things.

I have not tried turning off polling modules will see if i can find where to do this and revert.

[Chas]

I would follow through the same troubleshooting as this first:

Polling just got ~300 % slower

Try ./poller.php -d -h host -m ports or -m sensors, as are the ones with biggest polling times. Then you can check what is taking so much time, if SNMP, MYSQL or RRD. I bet is a disk issue. Whats your disk I/O for librenms?

Run the poller.php on a device, and also check disk IO / available ram and CPU.

Good day

I would like to thank everyone who assisted me in doing some troubleshooting the problem, found there was 1 device with allot vpn graphs once i deleted it restored all the speed.

there was well over 3000 monitoring graphs on it thanks to all.
