Install patch ZBXNEXT-2301

[evertonbernardi]

Hello.

I'm having problems with bulk SNMP after the update to the 2.2.6 version.
I found the patch ZBXNEXT-2301 that would solve this issue, but I can't see how to install it on my server.

I've tried installing the patch with the command "patch < filename.patch", but I receive a message asking for which file should be patched and I don't have this info.


Can anybody help me?


Kind Regards!

just curious, that kind of problem you have with Bulk SNMP?

basically, to apply this patch you need enter in directory of source and apply the patch only in file tha will be modified (keeping in mind the patch and source are on ~ of user), example:
cd zabbix-2.2.6
patch src/libs/zbxdbcache/dbconfig.c ../no-snmp-bulk-in-2.2.6.patch

Hello Alisson.

First of all thank you so much for your reply! The problems I'm having are related to our LAN network switches from HP. They don't support bulk SNMP (at least with their default setting) and I need to collect important info on them.

I'm sorry if this is a newbie question but regarding the patch I don't have the file /src/libs/zbxdbcache/dbconfig.c
Is this path correct?


Regards.

Don't use the first /, because don't is the absolute path, but relative to your directory zabbix-2.2.6 (current). use src/libs/zbxdbcache/dbconfig.c

I was thinking about the problem of bulk, I guess that you are using SNMPv1, that does not support SNMPBulkget. Try to use SNMPv2 in your tests and/or enable v2 on your switch HP.

Hello Alisson,

What I tried to say in my previous reply was that I can't find the file dbconfig.c in my Zabbix install so I guess the patch won't be applied as the destination file doesn't exist. Can you please help me find this file or point me to the right direction?

The SNMP V2 was already enabled. For precaution I disabled SNMP V1 on the switches I'm testing but the problem persists. In Zabbix the SNMP items for these switches are shown as "Not supported" (snmp_parse_oid(): cannot parse OID "SNMPv2-MIB::sysUpTime.0")


Thanks for your attention.

Do you post /src/libs/zbxdbcache/dbconfig.c, but the correct is src/libs/zbxdbcache/dbconfig.c. See the diference between the first slash.

See:
/src/libs/zbxdbcache/dbconfig.c is different of:
src/libs/zbxdbcache/dbconfig.c

Do you tried using snmpget on command line? it seems like you have a error on snmp installed in your server.

What OS do you use? On Ubuntu, for example, is needed install package snmp-mibs-downloader

Alisson,

Our Zabbix server is installed on Ubuntu 14.04 and I'm able to get an answer with the command snmpget from WITHIN the Zabbix server as you can see bellow:

root@srvzabbix01:~# snmpget -c public -v2c -Cf 10.10.10.10 SNMPv2-MIB::sysUpTime.0
SNMPv2-MIB::sysUpTime.0 = Timeticks: (2889387723) 334 days, 10:04:37.23

Even with the 'standalone' SNMP working, Zabbix still shows the SNMP items as 'Not supported'.

---
Regarding the patch application:
Suppose the patch file is in the /tmp/patch/ and I run the command "patch < no-snmp-bulk-in-2.2.6.patch".

root@srvzabbix01:/tmp/patch/# patch < no-snmp-bulk-in-2.2.6.patch
can't find file to patch at input line 5
Perhaps you should have used the -p or --strip option?
The text leading up to this was:
--------------------------
|Index: src/libs/zbxdbcache/dbconfig.c
|================================================= ==================
|--- src/libs/zbxdbcache/dbconfig.c (revision 48624)
|+++ src/libs/zbxdbcache/dbconfig.c (working copy)
--------------------------
File to patch:

What should I input in "File to patch"?


All the best.

Let's come back...

You need download the zabbix source, unpack, enter in directory and apply the patch.
For example:
wget http://downloads.sourceforge.net/pro...x-2.2.6.tar.gz
tar xzf zabbix-2.2.6.tar.gz
cd zabbix-2.2.6
patch -p0 < /tmp/patch/no-snmp-bulk-in-2.2.6.patch

After you will nedd compile zabbix using the configure script.

Correct..

It started becoming more complicated than I tought it would..
I think I'll bring up the old Zabbix server (version 2.2.2) back online and wait for the release of the final version with this feature added. I don't feel confident to execute this process without doing any harm to my environment.

Thank you very much for all your patience and help Alisson!
