SNMP is not really simple, but quite a useful protocol, if you want to run standard monitoring tools like Nagios, Zero RRD or Cacti.
Even though Java offers JMX for runtime information like thread and memory consumption, you can also use SNMP to read at least a subset.
In my opinion usage of a standard monitoring tool has several advantages over JMX-based visualization in jconsole or Lambda Probe:

• Statistics fit into centralized reporting, e.g. for SLAs.
• The tools are independent of the Java VM. If the VM freezes, the history is still available

After strange behavior while reconfiguring my DD-WRT on the LinkSys hardware I am using and even instabilities, I decided to upgrade to the recommended DD-WRT firmware for my WRT54GL model.

I have been using DD-WRT on that same router for years and also conducted several updates, but recently (over the past few months) the router's behavior turned from stable to weird.

But it seems the latest upgrade procedure fixed the problems.

I currently use the following script to copy a VDR recording into a MPEG-PS container using a very robust input decoder, so any error in the recording is fixed:

I recently used my MRTG to analyse some network problems at home. Since zooming felt not easy enough, I installed Cacti to monitor my DD-WRT interfaces (LAN, WLAN, DSL).

I currently use the following ffmpeg script to convert the recordings of my VDR 1.6 to more handy MPEG4 files:
