History

#1 Updated by Filippo Carletti almost 7 years ago

We need:
  • collectd-ping from epel
  • a template for /etc/collectd.d/ping_wan.conf to monitor wan links
  • optional: a template to monitor additional hosts (ie vpn)

#2 Updated by Filippo Carletti almost 7 years ago

  • Status changed from NEW to TRIAGED
  • % Done changed from 0 to 20

While we work on collectd, I'd like to clean it up a bit, not collecting some unused data.

#3 Updated by Filippo Carletti almost 7 years ago

  1. cat /etc/collectd.d/ping_wan.conf
    <Plugin "ping">
  Host "fastweb" 
  Interval 5
</Plugin>

fastweb is defined in /etc/hosts as the next hop.
We also need to select the right interface to send pings.

The extension will automatically monitor:
  • first configured DNS
  • checkip for providers in Multi Wan setup
  • custom hosts saved in PingHosts property inside the collectd key. The PingHosts is a comma-separated list of host names or ip address

Packages in nethserver-testing:
  • nethserver-collectd-1.0.3-3.0gitd0be7b65.ns6.noarch.rpm
  • collectd-ping-4.10.9-1.el6.x86_64.rpm
  • liboping-1.5.1-1.el6.x86_64.rpm
Test case 1
  • Configure a server with only the green or one red interface
  • Check collectd is configured to ping the first DNS (check: /etc/collectd.d/ping.conf)
  • You can also install nethserver-cgp and take a look to the graphs
Test case 2
  • Configure a server with two or more red interfaces with associated providers. You can mock this environment with the following commands:
    db networks set P1 provider checkip 192.168.1.1 status enabled
db networks set P2 provider checkip 192.168.1.2 status enabled
signal-event nethserver-collectd-update
  • Check collectd is configured to ping also both checkip of configured providers (check: /etc/collectd.d/ping.conf)
  • You can also install nethserver-cgp and take a look to the graphs
Test case 3
  • Set one or more custom hosts:
    config setprop collectd PingHosts google.it,facebook.com
signal-event nethserver-collectd-update
  • Check collectd is configured to ping also the custom hosts (check: /etc/collectd.d/ping.conf)
  • You can also install nethserver-cgp and take a look to the graphs

#7 Updated by Filippo Carletti over 6 years ago

  • Status changed from ON_QA to TRIAGED
  • % Done changed from 70 to 20
All test cases passed, but I found two minor issues:
  1. Interval is 10 and not 5 as per comment 3
  2. the cleanup script gives a warning
# grep -r Interval /etc/collectd*
/etc/collectd.d/ping.conf:Interval 10
# find /var/lib/collectd/ -type d -empty | xargs rmdir 
rmdir: missing operand
Try `rmdir --help' for more information.

The fix for 2. is:

find /var/lib/collectd/ -type d -empty | xargs -r rmdir
