Allow Mib usage for specific data query

sysres-dev commented 4 years ago

Is your feature request related to a problem? Please describe. In some cases for snmp data queries, it happens to have hexstring instead of its value :

I noticed for some reason cacti doesnt include mibs in its snmp commands, which lead in my case in situations where i end up with hex graphs names, when i run same commands with and without mibs includes, i reproduce the behavior :

# snmpbulkwalk -v3 -l authPriv -u community -x AES -X XXXXX -a SHA -A XXXXX 1.2.3.4  .1.3.6.1.4.1.41263.8.1.3 
SNMPv2-SMI::enterprises.41263.8.1.3.1 = Hex-STRING: 4E 75 74 61 6E 69 78 4D 61 6E 61 67 65 6D 65 6E
74 53 68 61 72 65 00
SNMPv2-SMI::enterprises.41263.8.1.3.2 = Hex-STRING: 53 65 6C 66 53 65 72 76 69 63 65 43 6F 6E 74 61
69 6E 65 72 00
SNMPv2-SMI::enterprises.41263.8.1.3.3 = Hex-STRING: 64 65 66 61 75 6C 74 2D 63 6F 6E 74 61 69 6E 65
72 2D 38 37 33 36 38 30 30 33 37 38 39 36 31 37
00
# snmpbulkwalk -v3 -l authPriv -u community -x AES -X XXXXX -a SHA -A XXXXX 1.2.3.4 .1.3.6.1.4.1.41263.8.1.3 -m +ALL
NUTANIX-MIB::citContainerName.1 = STRING: NutanixManagementShare.
NUTANIX-MIB::citContainerName.2 = STRING: SelfServiceContainer.
NUTANIX-MIB::citContainerName.3 = STRING: default-container-87368003789617.

Describe the solution you'd like Possibility to enable of disable mib usage for a given data query on device page when launching a reload.

Describe alternatives you've considered Put oid used by data query in a wrapper script.

Version of Cacti, and a description of the Data Query? Is it one of ours?

cigamit commented 4 years ago

For the <input> types, there is a tag that you can add to the Resource XML file calle:

<output_format>ascii</output_format>

Adding this to your Resource XML file, followed by a re-index, should solve your problem.

cigamit commented 4 years ago

This is documented, though maybe without a real good example. You should consider using this case to provide an example for our documentation. A pull request in that repository would be a nice way to give back to the project.

Here is a link to the page...

I missed this possibility in the doc, Thanks !

I added the output_format to the xml, but after a polling (to wait to have the xml updated on the poller), and after multiple reindex of the data query, it seems to have lost track of the values :

Here is the complete xml file :

Also, our cacti version is 1.1.38 and the data query is handmade, i attached it to the comment.

The issue with previous information is still valid, what can we do about it ?

sysres-dev commented 4 years ago

Hello, I looked at the code, output_format with ascii parameter sets SNMP_STRING_OUTPUT_ASCII, but it doesn't seems to be used in either snmp.php or data_query.php to change output (i'm in 1.1.38).

EDIT : I realized i forgot to give you additional context, i've updated the initial post with it, sorry !
