How to Munin Graph JVM Memory Usage with Ubuntu tomcat

The following description works when using the Ubuntu "tomcat7" package:

Grab the "java/jstat__heap" plugin from munin-contrib @ github and place it into "/usr/share/munin/plugins/jstat__heap".

Link the plugin into /etc/munin/plugins

ln -s /usr/share/munin/plugins/jstat__heap /etc/munin/plugins/jstat_myname_heap

Choose some useful name instead of "myname". This allows to monitor multiple JVM setups.

Configure each link you created in for example a new plugin config file named "/etc/munin/plugin-conf.d/jstat" which should contain one section per JVM looking like this

[jstat_myname_heap]
user tomcat7
env.pidfilepath /var/run/tomcat7.pid
env.javahome /usr/

Website Technology Changes in January 2014

As in the last four months I'm looking into changes visible at the frontend pages of the biggest websites. The last month saw a lot of version upgrades and hiding server versions.

The detailed results can be found here:

What Changed?

DNS-Prefetching The HTML header based DNS prefetching is expanding once more and for the first time used on adult site: xnxx.com
IPv6 An AAAA record was sigthed for the first time for yandex.ru
Version Upgrades
  • bildblog.de upgrades from Gentoo PHP 5.4.13 to 5.5.7
  • flipkart.com upgraded nginx 1.4.1 to 1.4.4
  • gomez.com switched OS and upgraded Apache 2.2.13 (Win32) to 2.2.15 (Red Hat)
  • jquery.com upgraded PHP 5.3.27 to 5.3.28
  • kickass.to upgraded Gentoo nginx 1.5.1 to bleeding edge 1.5.10 same for PHP 5.5.5 to 5.5.9
  • taz.de upgraded Apache 2.2.16 to 2.2.22
  • wetteronline.de upgraded Apache 2.4.2 to 2.4.7
  • xhamster.com upgraded nginx 1.4.1 to 1.4.4 and PHP 5.3.15 to 5.3.21
Hiding Server Version Additional sites are now hiding the webserver version

Note: the website links lead to a history page for the different sites were you can see the change details.

Caution!

All the results listed above are based on a simple scanning script. The results present a snapshot of the websites and a single response only. This is of course not necessarily an indicating for what techniques the site uses in daily operations!

Liferea 1.10.6 Released

Today saw the stable release 1.10.6. It provides two important bug fixes:

* Fixes SF #1135: liferea-add-feed doesn't process feed:https//

* Fixes SF #1137: crash on startup in enclosure_list_view_load
  (reported in Redhat #1048499, Fedora #214888)

Website Technology Changes in December 2013

As in the last three months I'm looking into changes visible at the frontend pages of the biggest websites. As to be expected changes during December are a bit limited as probably everyone favours stability over the holidays.

The detailed results can be found here:

What Changed?

DNS-Prefetching The HTML header based DNS prefetching is still there and gained yet another site: flipkart.com
IPv6 No change in AAAA records.
Version Upgrades fu-berlin.de upgrades from Apache 2.2.17 to 2.2.22
conduit.com upgrades from IIS 7.5 to 8.5
microsoft.com upgrades from IIS 8.0 to 8.5
Webserver Change Documentation site w3schools.com now shows nginx 1.2.6 instead IIS 7.5 as user facing webserver
Hiding Server Version One more site hostgator.com stopped reporting the Apache version

Note: the website links lead to a history page for the measurements.
