buggy count comparison filter in 0.4.3 and 0.4.4

[joba12]

Got some problems with count and <, > and =

The following example: Want to check if 2 of 3 processes are started
nscp.exe client -q check_process "filter=exe = 'aaa.exe' or exe = 'bbb.exe' or exe = 'ccc.exe'" process=* "warn=count < 2 " "crit=count < 1 " WARNING: aaa.exe=started|'count'=2;2;1

In the result you can see that there are two processes started, but output is only processed for one and state is critical, even if 2 is not lower than 2
After alot of testing I could not find a working solution
Tested the following two examples and a lot more (!=, =, <,...":
"warn=count < 2 " "crit=count < 1 "
"warn=count = 1 " "crit=count = 0 "

Furthermore filter rules are case sensitive, it would be nice to have possibility to use them non case sensitive

Did som research... One of the developers confirmed that there is no workaround and that this bug wasn't fixed until the relase of 0.5.0.2 -> https://github.com/mickem/nscp/releases/tag/0.4.4.2

Yes, one of the main changes in 0.5.0 was essentially the fix for this issue.

You can work around it using custom scripts in earlier versions.

As for the other issue do you mean COUNT versus count or foo = "bar" versus foo = "BAR"?

Hi mickem!
I think he means it like this:
"filter=exe = 'aaa.exe' or exe = 'AAA.exe' or exe = 'AaA.exe'"

Some processes may written differently, like explorer.exe or Explorer.exe, but mean the very same process.
So if someone wants to check "explorer.exe", but the process is called "Explorer.exe" on the system, the check wouldn't find this process.

Thanks for the information mickem

The other issue was explained by MaskierterMuchacho very good, exactly hit the spot

[mickem]

I was just about to say thats what regular expression and like are for but noticed that like did not ignore case, wil lbe fixed in the next build.

So:

"filter=exe like 'aaa.exe'"

should match:

• aaa.exe
• AAA.exe
• AaA.exe
