Log Rotate for ZM

[securiteaze]

Save the following code as zm_rotate.cron and put it in /etc/cron.daily or /etc/cron.weekly. It will compress old logs with bzip2. I not sure if zm needs to be stopped for the current log to rotate, so it is optional.

Code: Select all

#!/bin/bash

#file used to control zoneminder
ZM_CONTROL_CMD="/etc/init.d/zm"
#ZM_CONTROL_CMD="/usr/bin/zmpkg.pl"

# "y" will cause zm to restart when logs are rotated
# "n" rotate logs without restarting zm
DO_STOP_ZM_YN="n"

#zm log directory
ZM_LOG_DIR="/var/log/zm"

#log files to rotate
ZM_LOG_FILES="zmaudit.log  zmdc.log  zmfilter.log  zmpkg.log  zmwatch.log"

#number of old logs to keep
NUM_OF_OLD_LOGS="4"

for i in `seq ${NUM_OF_OLD_LOGS} -1 1`
 do
  for fil in `ls ${ZM_LOG_DIR}/*${i}.bz2 2> /dev/null`
   do
    base=`echo $fil | cut -d "."  -f1,2`
    let x=${i}+1
    [ ${NUM_OF_OLD_LOGS} -eq ${i} ] && rm ${fil} 2> /dev/null ||
    mv ${fil} ${base}.${x}.bz2 2> /dev/null
   done
 done

[ ${DO_STOP_ZM_YN} == "y" ] && ${ZM_CONTROL_CMD} stop &> /dev/null

for i in `echo ${ZM_LOG_FILES}`
 do
  [ -e ${ZM_LOG_DIR}/${i} ] &&
  mv ${ZM_LOG_DIR}/${i} ${ZM_LOG_DIR}/${i}.1 &&
  bzip2 ${ZM_LOG_DIR}/${i}.1 ||
  true
 done

[ ${DO_STOP_ZM_YN} == "y" ] && ${ZM_CONTROL_CMD} start &> /dev/null
