Hi Wolfgang,

I'm currently doing more or less the same with the following:

Assign each call unique id, which is used at least once per thread
(for call level variables), for example:

macro init_channel() {
  if ("${call_id}" = "") {
    Set(__call_id=${UNIQUEID});
    NoOp(Initializing call_id to ${call_id});
  } else {
    NoOp(Call id already set to ${call_id});
  }
  ...

So, i call this macro every time call can change threads (transfer,
etc). This is supposed to be replaced with linked-id somewhere in
trunk.

Then just grep for all threads that output needed call id:

if [ "$1" == "" ]; then
  echo "Usage: fetch.sh <call_id>"
  exit 1;
fi

if [ "$2" == "" ]; then
LOG_FILE="cat /var/log/asterisk/full"
else
LOG_FILE="cat /var/log/asterisk/full.$2.gz | gunzip"
fi

A="$LOG_FILE | grep $1 > /tmp/callid.txt"
eval $A
cat /tmp/callid.txt | grep -o -P
"(?:ERROR|WARNING|VERBOSE|DEBUG)\[([0-9]*)\]" | grep -o "\[[0-9]*\]" |
uniq | sort | uniq > /tmp/callid_pids.txt
A="$LOG_FILE | grep -F -f /tmp/callid_pids.txt > callid_$1.log"
eval $A
