Monitor folder size

[jordibrand]

I want to monitor size of specific folders on a windows host, and get the output in different items.

e.g.:
E:\TEST1
E:\TEST2
E:\TEST3

Can anyone put me in the right direction? I know how it works with the whole partition, but not for each specific folder on that partition.

I don't believe Zabbix naively supports monitoring windows folder sizes.

You could setup a UserParameter that could execute a command which would give you the folder size. If you have powershell on the hosts, below is an example UserParameter.

UserParameter=folder.size[*],powershell -noprofile -command "ls -r "$1"|measure -s Length| select sum| ft -hide"

I haven't tested it, but something like the above should work and add the folder.size item to that host which you can setup.

Thanks, I think it's kind of works. In zabbix I get the following error: Received value [ 339088873] is not suitable for value type

Item settings are:
Type: Zabbix agent (active)
Type of information: Numeric (unsigned)
Data type: Decimal

So zabbix knows the value of the folder, but maybe there's something wrong in the item?

What happens if you change the type of information to a Numeric (Float)? I'm afraid I can't test this at the moment but it looks as if it will work.

One a side note, what happens when you run the powershell on it's own? Remember Zabbix only reads the first returned line when using User Parameters.

[jordibrand]

I've changed it to type Numeric (Float), but the error is the same.
If I run it from the command line or powershell, the only output is 339088873, so it's the same.

[morrolan]

More specifically, does the number returned contain a space in front of it (it appears to contain one in your initial response to the powershell script)? I'm wondering if that is throwing it off?

[jordibrand]

This is the output, a lot of spaces in front of it.

I did some research and there is small correction for PowerShell script:

C:\>powershell -noprofile -command "[B]([/B]ls -r c:\test|measure -s Length|select Sum|ft -hide[B]|Out-string).trim()[/B]"
8013400

As you can see, I added front round bracket and applied .trim() function for result string.

Please, check the new Userparameter= line and let me know if it works.

UserParameter=folder.size[*],powershell -noprofile -command "(ls -r "$1"|measure -s Length| select sum| ft -hide|Out-string).trim()"

Thanks, it works! Just one problem, it works for folders under 1GB, folder above 1GB aren't working: ZBX_NOTSUPPORTED

[jordibrand]

De powershell script is working, but it's only not working in zabbix with folders larger then 1GB. I tried different item settings but nothing worked.
Anyone an idea?

[morrolan]

I am testing it myself now so I will get back to you after I've finished

Did you try Numeric (unsigned) type of data?
Also try to play around Use custom multiplier to multiply the input to 0.001.

[jordibrand]

Yes, my settings are:

Type of information: Numeric (unsigned)
Data type: Decimal
Units: B

I will try your suggestion (use custom multiplier), I will let you know!

@morrolan, thanks!

It's not working, I tried 0.1, 0.01, 0.001, 0.0001 and 0.00001.

Two more checks:
A) Do you mind to run powershell command on that client manually?
Start Powershell.
Copy-paste command with replaced Folder Name

powershell -noprofile -command "(ls -r "c:\Folder Name"|measure -s Length| select sum| ft -hide|Out-string).trim()"

Show us the result of command.

B) And then test how it works locally on client's side?

zabbix_agentd.exe -t folder.size[c:\Folder Name]

Show us the result of command also.
