It is possible to have QueueMetrics search for recordings in multiple directories, e.g. one directory for each day. This has the great advantage of being faster (because QueueMetrics does not have to scan through the whole file set) and more manageable (because you can easily move files around by date e.g. from a local volume to a NAS unit as needed). In order to do this, you have to configure “LocalFilesByDay” storage in QueueMetrics. In this example, we imagine that your recordings are held in a directory structure like /recordings/YYYY/MM/DD/myfile.wav It is also mandatory that all files have in their name the unique-id of the call that was recorded, so that QM can match audio files to calls.

It is often useful to store audio recordings in different subfolders, e.g. per day. We imagine that you want to record queue traffic on an external volume called /recording . Continue Reading...
This recipe explains how to reboot a Draytek Vigor 2600 router from the Unix command line. Simply run the following command to reboot router 192.168.5.1 whith administrative user USER password PASS:
wget -O - "http://USER:PASS@192.168.5.1/cgi-bin/reboot.cgi?sReboot=Current&submit=++OK++"
--14:17:50-- http://USER:*email@example.com/cgi-bin/reboot.cgi?sReboot=Current&submit=++OK++ => `-' Connecting to 192.168.5.1:80... connected.

If you did the original installation of QueueMetrics using yum, updating it is very easy. Continue Reading...
Monitoring hardware sensors can be extremely useful for a production server. Recent servers - in my case a quad-code HP ML310 G5 - often adhere to a standard called IPMI for hardware monitoring. My Debian kernel does not automatically load the required IPMI drivers, though the kernel modules are actually present with the distribuited kernel (in my case a 2.6.18-6-686-bigmem #1 SMP). In order to make them work, I have to manually load IPMI modules:
modprobe ipmi_si modprobe ipmi_devintf
ml310:~# lsmod | grep ipmi ipmi_devintf 9320 0 ipmi_si 34572 0 ipmi_msghandler 32288 2 ipmi_devintf,ipmi_si
apt-get install ipmitools
ml310:~# ipmitool -I open sdr list Int. Health LED | 0 unspecified | ok VRM (CPU1) | 0 unspecified | cr CPU Fan | 60.37 unspecifi | nc Rear Fan | 33.32 unspecifi | nc Temp 1 | 24 degrees C | ok Temp 2 | 30 degrees C | ok Temp 3 | 19 degrees C | ok
ml310:~# ipmitool -I open sdr get 'Temp 1' Sensor ID : Temp 1 (0x5) Entity ID : 7.1 (System Board) Sensor Type (Analog) : Temperature Sensor Reading : 24 (+/- 0) degrees C Status : ok Positive Hysteresis : Unspecified Negative Hysteresis : Unspecified Minimum sensor range : -127.000 Maximum sensor range : Unspecified Event Message Control : Entire Sensor Only Readable Thresholds : Settable Thresholds : ucr unr Threshold Read Mask : ucr unr
Some EPIA boards are based on the VIA C3 processor, that is basically a clone of an i686 that does not support the whole instruction set. Therefore, in order to be sure that what you try to execute will actually work, you have to compile as if the processor were an i586, though Debian Etch thinks to be on an i686:

We run a small office with our Asterisk PBX but we record all phone traffic, in and out. Needless to say, this can exact a large toll on our disk resources. I’m submitting this script and related Cron entry for those who need to compress their monitor recordings to mp3 format and need a program that will only run when the PBX is idle. Assumptions: Continue Reading...
