Logging

Messages from GNU GPL sniffer sensor service

Voipmonitor by default uses 'daemon' facility of a syslog to store status messages.

Default location

it is stored to /var/log/syslog(on debian/ubuntu)or to /var/log/messages(on centos/rh)

Messages file Change

You can find useful to store status info from voipmonitor to different file: For rsyslog use this in /etc/rsyslog.conf

if $programname == 'voipmonitor' and $syslogseverity <= '7' then /var/log/voipmon.log
& ~

Status line details

SQLq

C=CDR_queue 
M=Message_queue
R=Register_queue
L=LiveSniffer_queue
Cl=Cleanspool queue

heap[A|B|C]

A

number of % of used heap memory.If 100 voipmonitor is not able to process packets in realtime due to CPU or I/O.

B

number of % used memory in packetbuffer.

C

% used for async write buffers (if 100% I/O is blocking and heap will grow and than ring buffer will get full and then packet loss will occur)

[Mb/s]

total network throughput

tarQ

number of files in a queue

tarB

MBs in tar buffer

tarCPU

threads used for taring - its consumption

t2CPU

pb:10.5/	- packetbuffer - out of the buffer
d:39.2/		- structs create for processing in t2
s:24.6/		- SIP - parse
e:17.3/		- SIP - calls/messages search, struct creation
c:6.8/		              - process_packets - calls/messages
g:6.4/                       - process_packets - registers
r:7.3/		              - process_packets - RTP
rm:24.6/	- RTP - packets shift, prepare for processing
rh:16.7/	- RTP - search hash
rd:19.3/	- RTP - move to read queue

Adding new thread is automatic

'd' is running after pb,
if 'd' > 50%, new thread 's' (reasembles, sip parse) 
if 's' > 50%, new thread 'e' (callid search + structs create for calls), 
if 'e' > 50%, new thread 'c' (calls)
if 'c' > 50%, new thread 'g' (registers)
if 'g' > 50%, new thread 'r' (rtp)

Threads removing

if 'r' < N remove 'r' 
if 'g' < N remove 'g' 
if 'c' < N remove 'c'
if 'e' < N remove 'e'
if 's' < N remove 's'

RSS/VSZ[323|752]MB

RSS

stands for the resident size, which is an accurate representation of how much actual physical memory sniffer is consuming.

VSZ

stands for the virtual size of a process, which is the sum of memory it is actually using, memory it has mapped into itself (for instance the video card’s RAM for the X server), files on disk that have been mapped into it (most notably shared libraries), and memory shared with other processes. VIRT represents how much memory the program is able to access at the present moment.
