CHANGES


Monitoring BGP session via Quagga daemon in Linux v1.0a - 2014.02.22:

1. fixed: incorrect reading the string in command "show ip bgp summary" when the peer with State/PfxRcd: Idle (Admin)


How to update previous version 1.0:

1. Replace old snmp_quagga_bgpd_mon.pl on new
2. Restart snmpd
=======================================================================
INSTALLATION


[REMOTE-SERVER SIDE]

[1] Quagga installed and "vtysh" properly configured using the nopassword directive.

[2] Copy quagga_bgpd_mon_v1.0a/remote_server/snmp_quagga_bgpd.pl to the remote server (for example /etc/srv_scripts/snmp_quagga_bgpd_mon.pl)
Then check path to "vtysh" in the script settings:
my $_vtysh = "/usr/bin/vtysh";

[3a] If SNMPD is running NOT from root user. And you don't want give access user "snmp" to "vtysh". You need to put into Cron next task:
$ nano /etc/crontab
*/5 * * * * root /bin/sleep 290; /usr/bin/perl /etc/srv_scripts/snmp_quagga_bgpd_mon.pl cron 2>&1

Script will check Quagga via "vtysh" every 5 mins, then it will get data and save them into temp files in /tmp/ directory.
You can change directory and names of temp files in script-settings below (my $_file_.... )
To create temp files at first time, run the script in command line with parameter "cron":

$ /usr/bin/perl /etc/srv_scripts/snmp_quagga_bgpd_mon.pl cron

Ok. Go to pat.4)

[3b] If SNMPD is running from root user or snmp user have access to "vtysh". You need to change value of $_ROOT in this script below:
my $_ROOT = 1;

[4] Put into snmpd.conf string with pass_persist:
$ nano /etc/snmp/snmpd.conf
pass_persist .1.3.6.1.4.1.2021.190.1000.3 /usr/bin/perl /etc/srv_scripts/snmp_quagga_bgpd_mon.pl

[5] Restart snmpd:
$ /etc/init.d/snmpd restart


!!! WARNING !!! If your linux are used SELinux (like CentOS), you must disable policy for snmp (or create a new policy yourself)
For disable snmp-module in SELinux:
$ semodule -d snmp
$ systemctl restart snmpd


[6] Test via snmpwalk:
$ snmpwalk -v 2c -c public 127.0.0.1 .1.3.6.1.4.1.2021.190.1000.3

...


[CACTI-SERVER SIDE]

[7] Copy snmp_quagga_bgpd_neighbors_queries.xml and snmp_quagga_bgpd_router_queries.xml
from quagga_bgpd_mon_v1.0a/cacti_dir/resource/snmp_queries/
to: cacti/resource/snmp_queries/

[8] Import templates from quagga_bgpd_mon_v1.0a/cacti_web_templates/ in Cacti.
=======================================================================

When you will create graphs - look at type of graph (see screenshots)

A curve, if there are changes in the value of MsgSent+MsgRcvd. (if there is activity in the send \ receiving route updates)
It does not display the intensity of the updates. It shows that were only changes.

There is a bug in the solution. When the first neighbor is in the Idle (Admin) state, you won't get any neighbor stats ( UCD-SNMP-MIB::ucdavis.190.1000.3.2.0 = INTEGER: 0 )

Re: Monitoring of BGP session via Quagga daemon in Linux

I am experiencing problems with this script.
I am running it on CentOS 7 and have encountered several problems with execution.
1. When I execute the script with>
/usr/bin/perl /etc/srv_scripts/snmp_quagga_bgpd_mon.pl cron
The files get updated with data that seems OK

2. Unfortunately on the machine that has activated there is a message SELinux:
Feb 9 10:33:11 XXXX python: SELinux is preventing /usr/local/bin/vtysh from connectto access on the unix_stream_socket .

***** Plugin catchall (100. confidence) suggests **************************

If you believe that vtysh should be allowed connectto access on the unix_stream_socket by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep vtysh /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

3. Also on both mashines that are running the script - when I do the "walk" there is no useful data:
[root@XXXXX ~]# snmpwalk -v 1 172.XX.XX.XX -c XXX .1.3.6.1.4.1.2021.190.1000.3
UCD-SNMP-MIB::ucdavis.190.1000.3.1.0 = INTEGER: 1

UCD-SNMP-MIB::ucdavis.190.1000.3.1.1.1 = INTEGER: 2
UCD-SNMP-MIB::ucdavis.190.1000.3.1.2.1 = STRING: "unknown"
UCD-SNMP-MIB::ucdavis.190.1000.3.1.3.1 = STRING: "n/a"
UCD-SNMP-MIB::ucdavis.190.1000.3.1.4.1 = STRING: "n/a"
UCD-SNMP-MIB::ucdavis.190.1000.3.1.5.1 = INTEGER: 0
UCD-SNMP-MIB::ucdavis.190.1000.3.1.6.1 = INTEGER: 0
UCD-SNMP-MIB::ucdavis.190.1000.3.1.7.1 = Gauge32: 0
UCD-SNMP-MIB::ucdavis.190.1000.3.1.8.1 = Gauge32: 0
UCD-SNMP-MIB::ucdavis.190.1000.3.1.9.1 = Gauge32: 0
UCD-SNMP-MIB::ucdavis.190.1000.3.1.10.1 = Gauge32: 0
UCD-SNMP-MIB::ucdavis.190.1000.3.1.11.1 = Gauge32: 0
UCD-SNMP-MIB::ucdavis.190.1000.3.2.0 = INTEGER: 0
UCD-SNMP-MIB::ucdavis.190.1000.3.3.0 = INTEGER: 0

Where is the problem in execution of this script ?
How can it be fixed ?

Did you try executing this:

Code: Select all

grep vtysh /var/log/audit/audit.log | audit2allow -M mypol
semodule -i mypol.pp

Yes. Unfortunately that didn't bring any progress to the situation. The part with SELinux can be "worked around" (even by disabling the SELinux as the last resort).
The bigger problem is inability of the script to send appropriate data to SNMP query (that problem exists even on the machine that does have Centos installed and SELinux disabled !!!).

What is even more problematic is the fact that scripts work just fine on Ubuntu machine !

Is there something in CentOS (that I overlooked) that could prevent normal execution of simple perl script ?!?!?

The script runs normally when it is executed by root or even non root users ("PING-PONG test") !

ls -alh /tmp/snmp_quagga_bgpd*
and

Code: Select all

cat /tmp/snmp_quagga_bgpd_ipsum
and

Code: Select all

vtysh -c "show ip bgp summary"

gslavic, do this:

Code: Select all

/usr/bin/perl /etc/srv_scripts/snmp_quagga_bgpd_mon.pl
then type:

Code: Select all

getnext
.1.3.6.1.4.1.2021.190.1000.3.1.2


Output must be like this:

Code: Select all

root@mini:/home/red_neon# /usr/bin/perl /etc/srv_scripts/snmp_quagga_bgpd_mon.pl 
getnext

gslavic,

Good, your snmpd daemon is running from user, who does not access to directory /tmp/ (could not reading data from /tmp/snmp_quagga_bgpd* files). Check command line with which runned snmpd and check user (snmp by default) in /etc/passwd. Maybe user snmp is locked in some directory
