## Number of routes by AS
|
|
|
|
IPv4:
|
|
```bash
|
|
#!/bin/bash
|
|
if [ "$1" = "config" ];then
|
|
echo graph_title Number of routes
|
|
echo graph_vlabel num. routes
|
|
echo graph_category network
|
|
echo graph_scale no
|
|
for AS in $(ip r|sed 's/.* dev //;s/ .*//'|sort|uniq -c|grep as|awk '{print $2}');do
|
|
echo $AS.label $AS
|
|
done
|
|
else
|
|
ip r|sed 's/.* dev //;s/ .*//'|sort|uniq -c|grep as|awk '{print $2".value "$1}'
|
|
fi
|
|
```
|
|
|
|
IPv6:
|
|
```bash
|
|
#!/bin/bash
|
|
if [ "$1" = "config" ];then
|
|
echo graph_title Number of routes
|
|
echo graph_vlabel num. routes
|
|
echo graph_category network
|
|
echo graph_scale no
|
|
for AS in $(ip -6 r|sed 's/.* dev //;s/ .*//'|sort|uniq -c|grep as|awk '{print $2}');do
|
|
echo $AS.label $AS
|
|
done
|
|
else
|
|
ip -6 r|sed 's/.* dev //;s/ .*//'|sort|uniq -c|grep as|awk '{print $2".value "$1}'
|
|
fi
|
|
```
|
|
(hint: The difference just the -6 on the ip command)

## Graph routes and activity for every neighbour
|
|
|
|
This munin-plugin makes it very easy to graph the announced routes and activity for each neighbour over time:
|
|
https://github.com/luben/bird-multigraph-plugin
|
|
|
|
It's also possible to get notified by Munin when a problem with the peering persists. You have to define a critical value in line 138:
|
|
```
|
|
imported.critical 1:
|
|
```
|
|
This will send execute the command (set in munin-node.conf) to alert you, if the imported route count falls under 1.
|
|
|
|
You might also want to change line 125 from
|
|
```
|
|
graph_title $proto->{title} routes
|
|
```
|
|
to
|
|
```
|
|
graph_title $name routes
|
|
```
|
|
|
