## Scripts
|
|
|
|
### Number of prefixes for collectd
|
|
|
|
#### collectd.conf
|
|
|
|
```conf
|
|
LoadPlugin exec
|
|
<Plugin exec>
|
|
Exec nobody "/etc/collectd/bgp_prefixes-quagga.sh"
|
|
</Plugin>
|
|
```
|
|
|
|
collectd refuses to exec scripts as root. On Debian vtysh is compiled with PAM support: adding nobody to the quaggavty group suffices.
|
|
|
|
#### bgp_prefixes-quagga.sh
|
|
|
|
```sh
|
|
#!/bin/bash
|
|
|
|
INTERVAL=10
|
|
HOSTNAME=dn42.hq.c3d2.de
|
|
|
|
while true; do
|
|
n4=$(vtysh -d bgpd -c "show ip bgp"|grep Total|sed -e 's/Total number of prefixes //')
|
|
n6=$(vtysh -d bgpd -c "show ipv6 bgp"|grep Total|sed -e 's/Total number of prefixes //')
|
|
|
|
echo "PUTVAL $HOSTNAME/quagga-bgpd/routes-IPv4 interval=$INTERVAL N:$n4"
|
|
echo "PUTVAL $HOSTNAME/quagga-bgpd/routes-IPv6 interval=$INTERVAL N:$n6"
|
|
|
|
sleep $INTERVAL
|
|
done
|

```

|
#### Number of prefixes per neighbour for bird
|
|
|
|
```sh
|
|
#!/bin/sh
|
|
#
|
|
# Collectd script for collecting the number of routes going through each
|
|
# BGP neighour. Works for bird.
|
|
#
|
|
# See https://dn42.net/Services-Statistics
|
|
|
|
INTERVAL=60
|
|
HOSTNAME=mydn42router
|
|
[ -n "$COLLECTD_HOSTNAME" ] && HOSTNAME="$COLLECTD_HOSTNAME"
|
|
|
|
while true
|
|
do
|
|
birdc 'show protocols "*"' | grep ' BGP' | cut -d ' ' -f 1 | while read neighbour
|
|
do
|
|
nbroutes=$(birdc "show route protocol $neighbour primary count" | grep -v 'BIRD' | cut -d ' ' -f 1)
|
|
echo "PUTVAL $HOSTNAME/bird-bgpd/routes-$neighbour interval=$INTERVAL N:$nbroutes"
|
|
done
|
|
# FIXME: we probably count non-BGP routes here
|
|
totalroutes=$(birdc "show route primary count" | grep -v 'BIRD' | cut -d ' ' -f 1)
|
|
echo "PUTVAL $HOSTNAME/bird-bgpd/routes-all interval=$INTERVAL N:$totalroutes"
|
|
sleep $INTERVAL
|
|
done
|
|
```
