# The plugin can utilize automatic configuration,
|
||
|
|
# here are the basic steps (require root privileges):
|
||
|
|
# 1. Copy it as /usr/share/munin/plugins/pinger
|
||
|
|
# 2. Make executable: "chmod 755 /usr/share/munin/plugins/pinger"
|
||
|
|
# 3. Customize hosts, interfaces and ping count below
|
||
|
|
# 4. As pinging takes much time, add a
|
||
|
|
# --
|
||
|
|
# [pinger]
|
||
|
|
# timeout 60
|
||
|
|
# --
|
||
|
|
# record to /etc/munin/munin-node.conf to avoid timeouts.
|
||
|
|
# 5. Run "munin-node-configure --shell", you should see smth like
|
||
|
|
# "ln -s /usr/share/munin/plugins/pinger /etc/munin/plugins/pinger"
|
||
|
|
# 6. Run the proposed command to create a link.
|
||
|
|
# 7. To verify, run "munin-node-configure", you should notice the "pinger" record
