[SR-Users] kamctl: command not available

Hi there, I want to use kamctl to monitor the state of a sip-proxy. I just have no idea which commands are available or should i use "kamctl mi" or "kamctl fifo" commands. Google dont give helpful links for that. Im am using kamailio 4.2.3+wheezy on a Debian wheezy and kamctrl dont work: # kamctl fifo uptime Control engine 'FIFO' loaded entering fifo_cmd uptime 500 command 'uptime' not available FIFO command was: :uptime:kamailio_receiver_19959 # kamctl fifo which Control engine 'FIFO' loaded entering fifo_cmd which 500 command 'which' not available FIFO command was: :which:kamailio_receiver_19985 # kamctl mi which Control engine 'FIFO' loaded entering fifo_cmd which 500 command 'which' not available FIFO command was: :which:kamailio_receiver_20016 here is my config: # grep -i fifo kamailio.cfg loadmodule "mi_fifo.so" modparam("mi_fifo", "fifo_name", "/tmp/kamailio_fifo") modparam("mi_fifo", "fifo_user", "kamailio") modparam("mi_fifo", "fifo_mode", 0640) # ls -la /tmp/kam* srw-r----- 1 kamailio root 0 Feb 27 12:39 /tmp/kamailio_ctl prw-r----- 1 kamailio kamailio 0 Feb 27 14:25 /tmp/kamailio_fifo The only known command what is working is to look into a hashtable: # kamctl mi sht_dump foo Control engine 'FIFO' loaded entering fifo_cmd sht_dump foo Entry:: 135 sip:0049xxxxxxxxxxx@sip.domain.tld:: 1 Entry:: 205 sip:0049yyyyyyyyyyy@sip.domain.tld:: 1 FIFO command was: :sht_dump:kamailio_receiver_20144 foo any idea what is wrong? and is there a documentation how to use "kamcrl mi" and "kamctl fifo"? Thanks Thomas
