[Mod-apache-snmp-users] compatibility with worker MPM ?

[<cba...@eu...>]

Hello,

I've installed mod_ap2_snmp on my Apache 2.0.58 with Net-SNMP-5.3.1. I can 
read serverName, serverVersion, serverTmpDir, etc... but all the infos 
regarding the activity are empty (busyWorkers, totalTraffic, idleWorkers...)

Is mod_ap2_snmp compatible with the worker MPM ? Any other idea ?

Regards,

Christophe

I've finally find which module was the origin of this segfault:
cfg_ldap. By disable this module, ap2_snmp is working fine.
However, I must set =AB snmp_http_address =BB to "127.0.0.1" and configur=
e
apache2 to listen also upon 80 port of 127.0.0.1.=20


Thanks Esteban et best regards,

[Esteban P. <est...@gm...>]

Hi Raphael,

Please, can you try this?
snmpset -v1 -c apache2 localhost APACHE2-MIB::totalTraffic.0 i 123

if it works fine, then replace this line:
snmp_http_address       10.0.0.1 80

with this.
snmp_http_address       127.0.0.1 80

Esteban

['S. B. <su...@de...>]

Hi,

Im' trying to get mod-apache-snmp working under a debian sarge, using
apache2 (2.0.54-5). I've successfully compiled ap2_snmp as net-snmp
module and ap2_snmp_module as apache2 module.
I've configure apache2 like this (:

--( /etc/apache2/mods-available/ap2_snmp.conf )--
        <Location /ap2_snmp>
                Sethandler ap2_snmp

                Deny from all
                Allow from 127.0.0.1 10.0.0.0/24
        </Location>

        snmp_agent_address      localhost
        snmp_tmp_dir            /tmp/
        snmp_version            1
        snmp_http_address       10.0.0.1 80
---8<---

--( /etc/apache2/mods-available/ap2_snmp.load )--
LoadModule ap2_snmp_module /usr/lib/apache2/modules/mod_ap2_snmp.so
---8<---

When I restart apache2, I'm getting these following error messages:

# /etc/init.d/apache2 restart
Forcing reload of web server: Apache2[Sun May 07 15:00:53 2006] [error]

[Sun May 07 15:00:55 2006] [error] 10.0.0.1:80

This is just a warning, yes...

I've set up some directives for snmpd:

--( /etc/snmp/snmpd.conf )--
com2sec apache2 default apache2
group ap2RWGroup v1 apache2
view apache2 included .1.3.6.1.4.1.19786.1.1

---8<---

I've tried to execute an snmpwalk command like this:

$ snmpwalk -v 1 -c public -m /usr/share/snmp/mibs/APACHE2-MIB.txt

Thanks, this answer my questions #2 and #3. But what about the first one
(aka why isn't just -I -ap2_snmp switch enough to disable ap2_snmp) ?

Yes, I'd prefer to stop server harassment directly.

Hello,

ap2_snmp module in net-snmp can't be unloaded.. :(  because it's build with
net-snmp and it's not a dynamic module. I'm working on this (dymanic module
for net-snmp) and that will fix this problem.

To avoid log access messages from ap2_snmp you can refer to the module faq'=

example for avoid this. But this only avoid the logging. :(

[Mod-apache-snmp-users] problem with the snmp agent

[Guillaume R. <Gui...@in...>]

Hello.

We just ran into a problem with official net-snmp mdk package, that kept
sending http request to local apache server every 30s without explicit
configuration for doing it. It appears the reason is the inclusion of
ap2_snmp snmp module in the package at build time, which is not easily
disable at runtime unless listing a tons of values for snmpd -I options.
Full discussion available at http://qa.mandriva.com/show_bug.cgi?id=3D202=
56

As the solution given is jsut a workaround, I have a few question that
may help us find a real solution:
- why isn't just -I -ap2_snmp switch enough to disable it, whereas
--with-mib-modules =3D ap2_snmp is enough to build it ?

- couldn't this module get build as a dynamic module instead, as
explained at http://www.net-snmp.org/tutorial/tutorial-5/toolkit/dlmod,
so as to be optionally used at runtime, as apache modules ?

- couldn't this module get build separatly from the core of net-snmpd,
so as to be packaged separatly ?

Thanks for your help.

Re: [Mod-apache-snmp-users] mod_apache_snmp v1.03 Zero Counters ???

[Esteban P. <est...@gm...>]

Hello Ross,

Has SNMP community configured in mod-apache-snmp directive write access?
The "tmp" folder that you define in the config file, has write permission
for the user running apache?
If this doesn't work, please send the configuration that you are using for
mod-apache-snmp.

[Mod-apache-snmp-users] mod_apache_snmp v1.03 Zero Counters ???

[R. F. <rf...@ci...>]

Hello,

I've tried looking through the mod_apache_snmp archives
& couldn't find anything.  I have a problem when trying to
get statistics back from our Net-SNMP v5.2.1.2 agent.  I
get the following on the command line (where www4 is our
Fedora Core 4 server) when starting Apache v2.0.55:

Starting httpd: [Wed Nov 16 19:59:37 2005] [error] AP2_SNMP: 
agentHttpAddress set to:
[Wed Nov 16 19:59:37 2005] [error] www4:80


Apache runs without any problems (e.g. I'm able to bring
up web pages, etc.)  However, when I query the SNMP
agent also running on the same server, we get the following:

snmpwalk -v 1 -c public -m ~/mod_apache_snmp_1.03/mib/APACHE2-MIB.TXT

The only counter that seems to be returning somewhat good
info is serverStatus & agentHttpAccess.  We simulate 404,
501 errors & normal HTTP 200 requests, but don't see any
of the counters being incremented ... nor do we get any of the
serverName, Version, Build, etc. data.  Any help would be
greatly appreciated or links to better documentation than on
the site.  We are using the latest mod_apache_snmp v1.03.

Thank you in advance for your help,
