sysObjectID not returning numeric IDs

[tbilan]

I had a problem where the mactrack SNMP requests weren't returning numeric OIDs so all my devices would show an Error status in the mactrack Devices Status column. This was weird since they showed as numeric when I configured them and hit Save as result shown in 1.jpg.

Code: Select all

mysql> select device_name, snmp_sysObjectID from mac_track_devices;
+----------------+-----------------------+
| device_name    | snmp_sysObjectID      |
+----------------+-----------------------+
| XC-I017-8MDFR3 | iso.3.6.1.4.1.9.1.697 |
| XCSC1GW        | iso.3.6.1.4.1.9.1.516 |
| XCE1GW         | iso.3.6.1.4.1.9.1.923 |

I added the following code in the cacti snmp.php file to force numeric results since I couldn't see a way to do this from the mactrack_functions.php. It's been running all day and I haven't had any issues with other areas of cacti.

Code: Select all

if (function_exists("snmp_set_oid_numeric_print")) {
     snmp_set_oid_numeric_print(TRUE);
     snmp_set_oid_output_format(SNMP_OID_OUTPUT_NUMERIC);
}

I could have probably chosen to just specify the device type with the non-numeric OID but since mactrack expects numerics and probably every other module I thought I'd just fix the source.

This was kind of a pain to track down so I thought I'd share it.
