NSClient++ Help (#1) - CheckFile syntax (#398) - Message List

humm, off the top of my head... a criteria?

I am not sure about defaults CheckFile2 works much like CheckEventLog but I would start adding a criteria like filter+size=>0 or some such.

Again off the top of my head, can see about looking into this is more detail later on.

Great! Your suggestion worked!! Now I have upgraded to 3.6 and it seems that filtering by file type doesn't work.

CheckFile2 file=C:\NSClient\test\*.msg MaxWarn=1 MaxCrit=2 filter+size=>0
d NSClient++.cpp(1034) Injecting: CheckFile2: file=C:\NSClient\test\*.msg, MaxWa
rn=1, MaxCrit=2, filter+size=>0
d \CheckDisk.cpp(112) Input is: C:\NSClient\test\*.msg / ffffffff
d \CheckDisk.cpp(126) File pattern: C:\NSClient\test\*.msg\*.*
d \CheckDisk.cpp(136) File pattern: C:\NSClient\test\*.msg\*.*
d NSClient++.cpp(1070) Injected Result: OK 'CheckFile ok'
d NSClient++.cpp(1071) Injected Performance Result: ''no files found'=0;1;2; '
OK:CheckFile ok|'no files found'=0;1;2;

What's with the added /*.* mask? I can just do a check on the number of all files in a directory but that could be dangerous in some situations. Is this a bug I can get around?

It seems that 0.3.6 has a problem with the file related checks.. I shall investigate tomorrow..

Anyone experiencing this issue....

I found an open ticket ​here and Mike's suggestion of using path=c:\mydir and pattern=*.txt worked for me in my test directory.

So after trying out with the above fix on my test directory I seem to have some more issues.

CheckFile2 path=C:\NSClient\test\ pattern=*.msg filter+size=>0 MaxWarn=300 MaxCr
it=500
d NSClient++.cpp(1034) Injecting: CheckFile2: path=C:\NSClient\test\, pattern=*.
msg, filter+size=>0, MaxWarn=300, MaxCrit=500
d \CheckDisk.cpp(112) Input is: C:\NSClient\test\ / 10
d \CheckDisk.cpp(126) File pattern: C:\NSClient\test\\*.msg
d \CheckDisk.cpp(613) result: 1 -- 1
...GOES ON FOR THE NUMBER OF *.msg FILES IN THE DIRECTORY...
d \CheckDisk.cpp(136) File pattern: C:\NSClient\test\\*.*
d \NSCHelper.cpp(73) String (9543) to long to fit inside buffer(4096) : 00d68957
b5
e NSClient++.cpp(1062) UNKNOWN: Return buffer to small to handle this command.
BAD_CODE:

There are 252 messages in that directory. Is checkfile unable to handle the number of files I'm looking for here?

The problem is the returned sting which is (usually) limited to something like 1024 chars.

There might be a truncate=123 option you can add and if not I should add one...

(There is one I just checked)

So I've gotten this running and set up an alias for nrpe checks and it works perfectly. However, there is an aesthetic issue that I would like to know if there is a fix for. The command I'm using sends back a listing of all the files found in a directory but I would MUCH rather it sent back a file count. Is this currently possible?

Next version (next nightly) will have an option called:

master-syntax which is the "over all" syntax for the command. It takes three options (and char data):

• %list% A list of all "files" (syntax controls this)
• %files% number of files
• %matches% number of files matched

Like so:

CheckFile2 MinWarn=10 MinCrit=10 path=D:\WINDOWS\system32 filter+size=gt:0 truncate=10 ignore-errors "master-syntax=%matches%/%files%"
OK:7177/7...|'found files'=7177;10;10;

(the truncate above sort of destroyed my output but you get the idea I guess)
