Monitoring Custom Directories in Linux

General

Hi there,
I was wondering how can I monitor the size of a custom list of directories in Linux. I moved recently to the raw versions, and importing external libraries is not an option here. Unless there is a manual steps to import external plugins from extchange.checkmk.com

Is there a way to do it using the linux agent only?

As always, thank you guys for the continuous help.
Regards,

The easiest way is a small script (local check) on the monitored host.
But there are also packages available like this one. There you get a plugin for your agent and a configurable check on your monitoring machine.
The how-to for the mkp files you can find here.

Hello,

What blocks you from using fileinfo?
You could use globbing patterns to cover several directories.

You could use /dir/**/**/* in the fileinfo.cfg to cover following structure:

[root@deaugwuxl0666 dir]# tree
.
β”œβ”€β”€ dira
β”‚   β”œβ”€β”€ dir1
β”‚   β”‚   β”œβ”€β”€ file1
β”‚   β”‚   β”œβ”€β”€ file2
β”‚   β”‚   └── file3
β”‚   β”œβ”€β”€ dir2
β”‚   β”‚   β”œβ”€β”€ file1
β”‚   β”‚   β”œβ”€β”€ file2
β”‚   β”‚   └── file3
β”‚   └── dir3
β”‚       β”œβ”€β”€ file1
β”‚       β”œβ”€β”€ file2
β”‚       └── file3
β”œβ”€β”€ dirb
β”‚   β”œβ”€β”€ dir1
β”‚   β”‚   β”œβ”€β”€ file1
β”‚   β”‚   β”œβ”€β”€ file2
β”‚   β”‚   └── file3
β”‚   β”œβ”€β”€ dir2
β”‚   β”‚   β”œβ”€β”€ file1
β”‚   β”‚   β”œβ”€β”€ file2
β”‚   β”‚   └── file3
β”‚   └── dir3
β”‚       β”œβ”€β”€ file1
β”‚       β”œβ”€β”€ file2
β”‚       └── file3
└── dirc
    β”œβ”€β”€ dir1
    β”‚   β”œβ”€β”€ file1
    β”‚   β”œβ”€β”€ file2
    β”‚   └── file3
    β”œβ”€β”€ dir2
    β”‚   β”œβ”€β”€ file1
    β”‚   β”œβ”€β”€ file2
    β”‚   └── file3
    └── dir3
        β”œβ”€β”€ file1
        β”œβ”€β”€ file2
        └── file3

Creates Agent Output:

With the rule β€œfile grouping patterns” you could group that together and with the rule " Size, age and count of file groups" you can set the thresholds.

I hope that helps

Thank you Mike. I was not aware of this one. I will try it out.

Thank you Andreas as usual. For being supportive. I will give this a try. I have a different question: Regarding the piggyback data in the server. How long does it take for CheckMk to remove the outdate entries from the server from this folder /omd/sites/ro/tmp/checkmk/piggyback/. Is it something that we can configure to run faster?

Thank you in advance
