Hi,

You neither sleep ?

I normally work with "distribution" packages but i can try to use this new one from source.
Is it already somewhere ?

Sorry for the delay but i'm currently downloading again cygwin as your new cactid.exe vesrion request the cygcrypto-0.8.9.dll that i haven't on my disk.
The result of the test in 10 minutes.

Master Witness,

!!!!!!!!! CHAMPAGNE !!!!!!!

With your package, i have been able to run my first perl script:
1°) without errors
2°) with a correct result

Just for your information (in case of)

i added the following dlls to the cactid folder in order to be able to use it as they seems to be mandatory now:
cygcrypto-0.9.8.dll
cygz.dll

Launching manually cactid under a cmd window, the following error occurs :
C:/netsnmp/etc/snmp/snmp.conf: line 1: Warning: Unknown token: mibdirs.

i will have a look later.

Thanks for your help and long life to cactid

TheWitness:

I had the same problem too. I suppose it wil be fixed using your latest Cactid086g-pre-beta-win32.zip but I'm at home now and I have no way to give it a try. In the meantime, can you re-release the file including the needed DLLs so that people (or maybe just me?) don't need to download and install full cygwin just for the need of those 2 files:

cygcrypto-0.9.8.dll
cygz.dll

Thanks in advance and regards.

magoo95,

Please edit the snmp.conf file and remove the mibdirs from that file. Then you will no longer have that error message.

jagbarcelo,

I am still working an issue with one user in Germany that until it is fixed, I can not release. Therefore, the code you have is a workaround. Thanks for testing it for me.

In the mean time, here are the extra files.

No luck: I have installed your latest patch and the dlls you have just uploaded but I still get the following errors in the log file:

I really appreciate your help, TheWitness & BSOD2600. Regards.

All,

I think i have the full explaination for this problem.
This is not entirely a cactid bug by itself.

When i have performed the new tests with this new cactid.exe, i have setup a full path in the "data input method" field as follow:
C:/perl/bin/perl.exe C:/cacti/scripts/w32cpu.pl <hostname> get LoadPercentage 2
and this working fine.
As i'm really curious, i have reinstalled from scratch cacti on my server and used this new cactid version, i again falled in the original problem:
CACTID: Host[2] ERROR: Empty result [129.227.81.125]: perl <path_cacti>/scripts/w32cpu.pl 129.227.81.125 get LoadPercentage 2'
CACTID: Host[2] DS[13] WARNING: Result from SCRIPT not valid. Partial Result: ..

damned

I then decided to modify the line itself and the problem is solved only if you set the full perl path as follow:
C:/perl/bin/perl <path_cacti>/scripts/w32cpu.pl 129.227.81.125 get LoadPercentage 2'

Conclusion, the problem is solved by using this new cactid version AND setting the full path for perl.

Odd. While I don't primarly use cactid for my polling, I do run a few perl scripts. Perl is in my system path, but I have not referenced the full path in Cacti data input methods. Everything works fine.

jagbarcelo · Post by **jagbarcelo** » Fri Nov 25, 2005 3:13 am

This is really annoying... I have also tried what magoo95 suggested about defining the full path to perl.exe in the 'data input methods' without any difference. I can't make my RRD files get updated when associated to w32_query_logicaldisk.pl. All the rest datasources are beging updated (pings, network traffic, etc) and the GUI (web pages) seem to work fine too.

I have one little thing to add and it confuses me a lot: There is another perl script that runs perfectly but not w32_query_logicaldisk.pl. The script is a replacement for the distributed ping.pl. Since I'm running on a spanish localised windows server, the cacti-built-in ping.pl script does not work for me. I modified it to be:

Code: Select all

#!/usr/bin/perl 

$ping = `ping -n 1 $ARGV[0] -w 1000 | grep TTL`; 
$ping =~ m/(.*tiempo(<|=))(.*)m(.*)/; 

print $3;

Which, in fact, don't make much difference with the original one. Well... this script works fine with cactid and the associated RRD files are updated. However w32_query_logicaldisk.pl does not work. Maybe because it returns multiple values? I don't know.

Just in case I attach a FULL-DEBUG log file of a cactid run. I hope TheWitness or BSOD2600 have a little time to have a look at it and help me out. I'd really like to start using this new version of cacti and not be anchored in the past using cacti-0.8.5 forever.

Regards.

It's weird how that script only some times returns stuff. Also, I didnt see any CACTI2RRD entries for your w32_query_logicaldisk.pl script. Mind posting a screenshot of the data input method?

jagbarcelo · Post by **jagbarcelo** » Mon Nov 28, 2005 3:35 am

A screenshot of my W32 - Get Free Disk Space data input method:
The input string is too long and cannot be read completely. It should read:

perl.exe <path_cacti>/scripts/w32_query_logicaldisk.pl <hostname> get freespace,size <driveletter>

I have also tried to set it to:
c:/perl/bin/perl.exe <path_cacti>/scripts/w32_query_logicaldisk.pl <hostname> get freespace,size <driveletter>

With and without the .exe extension from 'perl.exe'

Note: Now I have 2 cacti's installed on my server. The old one in order to keep on retrieving data. And the new one just for testing (under /cactinew/). Of course, cactinew instance has its own database cactinew on MySQL and I have replaced all directory references from cacti to cactinew. This new instance called cactinew behaves the same way that I've commenting in this thread: w32_query_logicaldisk.pl does not update any RRD file.

-------------------

I decided to do one test more before sending this out: I have just seen my output fields called Size and FreeSpace (note the upper cases) and tried just to write them all using lowercases (size and freespace). Now the RRDs are updated and everything seems to run perfectly. I want, however make clear that this data input method worked also perfectly on version 0.8.5, so there must have been a change somewhere in the middle of versions 0.8.5 to 0.8.6g that changed this behaviour, making the names of output fields case-sensitive... or maybe it is just a cactid issue, and cacti is not to blame.

TheWitness: Can you check that? If cactid has this behaviour on purpose, it's ok, but if there is no real reason for being case-sensitive, I suppose it should be better to read the output fields not being case-sensitive.

Regards, and thanks a lot for your help and valuable time. Keep on working on this great tool ;)
