Help with solving repeat compile search on custom MIBs #391

Open johnmurtari opened 3 years ago

johnmurtari commented 3 years ago

Folks, I like this package, sorry to the developer is in bad health. Very close to using it on a project, it requires custom MIBs and it's just too slow... I think I'm missing something obvious....

I really like the package. I've spent days reviewing documentation, posts on Google. I think I understand what to do, tried several different things, but can't make headway. I'm downloaded the files for 2.6 and am running on RedHat 6.9, python 2.6. I've tried to simplify the issue below:

     If I use snmpget.py  to retrieve a standard SNMPv2-MIB, the request completes very quickly:

$:~/jm1/python$ time snmpget.py -v 2c -c public 1.2.3.4 SNMPv2-MIB::sysDescr.0 SNMPv2-MIB::sysDescr.0 = DisplayString: BIG-IP Virtual Edition : Linux 3.10.0-862.14.4.el7.ve.x86_64 : BIG-IP software release 15.1.0.5, build 0.51.8

real 0m0.439s user 0m0.411s sys 0m0.026s

   When used to retrieve a vendor specific MIB, it is quite slow, about 10 times slower...

$:~/jm1/python$ time snmpget.py -v 2c -c public 1.2.3.4 F5-BIGIP-SYSTEM-MIB::sysStatClientPktsIn.0 F5-BIGIP-SYSTEM-MIB::sysStatClientPktsIn.0 = Counter64: 162

real 0m5.622s user 0m5.576s sys 0m0.032s

   In both cases, I also get quite a few 'compiler' message lines, and if I don't have ply available the request fails in both cases.   I don't understand why it still wants the compiler?

    I need to load unique MIBS for F5 equipment.  I believe I have compiled them properly using mibdump.py and they are located here:
mibdump.py --rebuild --mib-source /home/oam/jm1/python/f5_mibs F5-BIGIP-COMMON-MIB F5-BIGIP-LOCAL-MIB F5-BIGIP-SYSTEM-MIB

 I feel I'm just missing something obvious!  Thanks for any help.

Best regards!

Recent releases have dropped Python 2.x support, so no investigation will be done unless the environment is upgraded to a supported Python version, 3.8+ right now.

Besides, you might read GitHub Markdown guide to learn more about code formatting. The current formatting is problematic and not easy to understand what you wrote.
