0.8.8c - Data query does not return output

[normal]

Dear all,

I'm trying to migrate my custom data query template from my old server to new server.

But somehow the data query does not return any output when run in new server.

It is working fine in old server.

FYI. Following are versions of the software that I'm using..

New Server
-OS : Windows Server 2012 Std R2
-Web server : IIS 8
-Cacti 0.8.8c
-Spine 0.8.8c
-MySQL 5.6.20.0
-PHP 5.6.3
-Net-SNMP 5.7.0
-RRDTool 1.4.5

Old Server
-OS : Windows Server 2003 Std R2
-Web server : IIS 6
-Cacti 0.8.7b
-Spine 0.8.7b
-MySQL 5.0.51a
-PHP 5.2.5
-Net-SNMP 5.4.1.3
-RRDTool 1.2.26

Any idea what can cause this ? Could it be there have syntax change on the php between version 5.6.3 and 5.2.5 ?

Any help would be much appreciated.

Assuming that query example is targeting the same device...
1) rules/firewalls which prevent new server from connecting to device?
2) if you manually run that same php query from the PHP Script Server on the new server, does it work?
3) if yes to #2, then likely the web server doesnt have permissions to read/execute the script.

Hi BSOD2600,

Thanks for your reply.

Following is output of the php script

Seems extension for ssh2 function is not installed in my new server with php 5.6.3.

I'm still searching around for how to get the php extension install in my new server.

Update :

I managed to resolve the ssh2 function issue by install phpseclib as suggestion in this thread : http://stackoverflow.com/questions/2481 ... also-enabl

However, I hit another issue when created graph with the related template...

somehow, no data show in the graph..

Found Cacti log start showing following warnings after I created the graph..

But I try run snmp query from the Cacti server to the client host, it looks ok...

But there have one thing that I think is abnormal. Somehow, the php query from the PHP Script Server doesn't return any output

but if query not through the PHP Script Server, it able to return the output..

In my old server, both type of query are able to return output.

Not sure what is the root cause actually ??

Would appreciate if you can enlighten me..

If you snmpwalk that specific OID which times out, does it also fail? If cacti thinks a device is down, it wont run any scripts against it.

Try using the full path to the script

Hi BSOD2600,

Here is the outcome

snmpwalk out for OID .1.3.6.1.2.1.1.3.0

Note:
a) To install phpseclib, I created 'c:\php\includes' folder manually and uncommented "include_path='.;c:\php\includes" in c:\php\php.ini
b) I included output of php query that not through PHP Script Server for comparison.

For the permission denied errror, I tried grant full permission to everyone for following folders and restart the Cacti server, but didn't help.

C:\inetpub\wwwroot\cacti\scripts
C:\php\includes

ah-ha, permission denied errors finally!

What about trying to grant IUSR and IIS_USRS read/execute rights to that folder referenced?
another option is to use sysinternal process monitor and examine exactly what/where the denied error is occurring. Link in my signature for a walkthrough.

Hi BSOD2600,

Thanks for your suggestion.

I tried both of the options you suggested. But still no luck

The sysinternal process monitor can't find any denied error

Sorry, BSOD2600. My bad, I misled you in my previous post.

It should be nothing wrong with the folder or file permission.

The reason why I got the 'Permission Denied' error is because there have an extra 'scripts' wording in the query -_-"

After take out the 'scripts' from the query, no more permission denied error. However, the no result return issue still persist

Not sure if something to do with the xml file configuration ? There have format change for the xml file in old and new Cacti ?

Any help would be much appreciated.

[BSOD2600]

The script files are compatible between the old and new version of Cacti, nothing really has changed in that regard.

Are the php.ini configs the same between the severs? A tool like WinMerge to easily compare is ideal.

If php settings are the same, I think it's time to debug the ss_seagatedqlinuxhit.php script. Did you write it or find it on the forum? If the latter, I'd ask for assistance on troubleshooting in the thread you got it. If the former, you've got some work to do...
