  • What fields are presented in /var/lve/info?

    Im creating my own system to drawing charts in real-time mode. File /var/lve/info seems to be the best way to get current info but what fields are presented in it?

    First is of course lve_id but the rest?

    [root@king ~]# cat /var/lve/info
    0,0,20,0,12,0,262144,0,0
    640,0,20,2,10,0,51200,0,0
    642,0,20,1,10,0,51200,0,0
    646,3,25,1,12,51886,230400,0,0
    550,1,20,4,10,4030,51200,0,0
    999,0,20,1,10,0,51200,0,0
    941,1,20,1,10,1422,51200,0,0

    The best way to go is not /var/lve/info
    but /var/lve/lveinfo.db
    It has historical data for all the LVEs. (it is an sqlite db)
    Also, it would be easier to read, as it has db schema that you can explore

      But lveinfo.db has not current data (?).

      sqlite> sel ect max(created) fr om history;
      2011-04-03 16:02:41.68
      sqlite> SELECT datetime(
      ow);
      2011-04-03 16:03:37

      I would like to refresh my chart every 5 seconds.

        we only store data to db once every minute (we don want it to grow too large)
        Here is format for /var/lve/info file (which is updated every 5 seconds)
        LVE_ID, EP, lEP, CPU, lCPU, MEM, lMEM, fMEM, fEP

        EP -- entry processes
        Prefixes:
        l -- limit
        f -- fault
