[HOWTO] Install and configure the Net-SNMP agent for Unix

[fmangeant]

Sorry for reading your post too late

I'm not using 5.4 everywhere, for example extending the agent does not work any more for me on AIX 64 bits...

Don't worry, I managed the issue on my own. Have a nice week end.

Hi, I instaled Cacti in Fedora 6, and i can add a host, but i cant get de diskinfo from the host. I trie with:

snmpwalk -v 1 -c public tcp:localhost:161 .1.3.6.1.4.1.2021.9.1.2

but got this:

End of MIB

I tried wiht this too:

snmptranslate .1.3.6.1.4.1.2021.9.1.2
UCD-SNMP-MIB::dskPath
snmpwalk -v 1 -c public tcp:localhost:161 UCD-SNMP-MIB::dskPath

and i got the same

This is my /etc/snmp/snmp.conf

agentaddress tcp:161
com2sec notConfigUser default public
rocommunity public
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
view all included .iso 80
view systemview included .1.3.6.1.2.1.1

access notConfigGroup "" any noauth exact systemview none none
syslocation Bat. C2
syscontact root@ares.dcaa.unam.mx
includeAllDisks 10%


Any help?, thanks

[fmangeant]

This is my /etc/snmp/snmp.conf

includeAllDisks 10%

Hi

most of the time (at least on my servers) the includeAllDisks option does not work. Could you replace it with something like this :

Code: Select all

disk /
disk /usr
disk /var

[neji]

Hi

I replaced includeAllDisk with this:

Code: Select all

disk /

and restart the snmp service: "service snmpd restart", and i got this:

Code: Select all

$ snmpwalk -v 1 -c public tcp:localhost:161 dskPath
End of MIB
$ snmpget -v 1 -c public tcp:localhost:161 dskPath
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: UCD-SNMP-MIB::dskPath

Any idea?, thanks

[fmangeant]

Can you try with only that in snmpd.conf ?

Code: Select all

agentaddress tcp:161
rocommunity public
disk /

Thanks!
I tried with that snmpd.conf and that's works. Now i can get that info and add that host in my cacti-host, and view the graphics. Thanks!

My net-snmp agent dont work when i click in Verbose Query to get informations to my processors. I just click and before 5 minutes my webserver returns error 500: internal error server, in my server, show a loop process to /usr/bin/php -q
/home/xxx/www/cacti/scripts/ss_host_cpu.php ... shows it:

Code: Select all

[root@svr02 ~]# /usr/bin/php -q /home/sigfbr/public_html/cacti/scripts/ss_host_disk.php xxx.xxx.xxx.xxx 6 2:161:500:public:::MD5::DES: index

In my other server with net-snmp 5.3.1 this not happen...

Can anyone compile a version 5.4 to linux centos (fedore core 6) and attach here to me??

[fmangeant]

Can you :

• update Net-SNMP to version 5.3.1-15 (available here) on your Fedora Core 6 box ?
• unset the MIBS variable on your Cacti server ?

[Smux]

hey fmangeant,

Thank you very much!! But when i click in Verbose Query my error persists... My cacti is 0.8.7a with svn revision at 4371.

[fmangeant]

Try that :

Code: Select all

$ unset MIBS
$ /usr/bin/php -q /home/sigfbr/public_html/cacti/scripts/ss_host_disk.php xx.xx.xx.xx 6 2:161:500:public:::MD5::DES: index

By the way, maybe you should remove your IP address from your previous post.

[Smux]

Ip address removed:

[root@svr02 snmp]# /usr/bin/php -q /home/sigfbr/public_html/cacti/scripts/ss_host_disk.php xx.xx.xx.xx 6 2:161:500:public:::MD5::DES: index

how to i solve my problem?

[fmangeant]

My cacti is 0.8.7a with svn revision at 4371.

Could you revert to 0.8.7a ?

[Smux]

I have same problem with 0.8.7a.

This is my 0.8.7a with revision 4371:

Code: Select all

[root@svr02 snmp]# /usr/bin/php -q /home/sigfbr/public_html/cacti/scripts/ss_host_cpu.php localhost 2 2:161:500:public:::MD5::DES: index

[root@svr02 snmp]#

and my 0.8.7a:

Code: Select all

[root@svr02 snmp]# /usr/bin/php -q /home/sigfbr/public_html/cacti2/scripts/ss_host_cpu.php localhost 2 2:161:500:public:::MD5::DES: index
[root@svr02 snmp]#

if I check my other server with old cacti (0.8.7):

Code: Select all

root@svr03 [/home/admin]# /usr/bin/php -q /home/sysmon/public_html/cacti/scripts/ss_host_cpu.php localhost 2 2:161:500:public:::MD5::DES: index
