怎么在crontab里面定时用glance收集数据

fusnow

我需要监控系统里面哪些进程的IO用的比较多，现在准备用glance，写了一个脚本如下：

$ cat io_mon.ksh
host=`hostname`
tag=`date \'+%Y%m%d\'`
BaseDir=`dirname $0`
mkdir -p ${BaseDir}/log

/opt/perf/bin/glance -j 3 -g -maxpages 3 -iterations 3 -f ${BaseDir}/log/process_list.txt
cat ${BaseDir}/log/process_list.txt >> ${BaseDir}/log/process_by_IO$tag.log

现在问题是这个脚本手工执行是可以的，但是放在crontab里之后生成的process_list.txt 永远都是空的，不知道怎么解决啊。

看了一下文档，可以用glance的metrics解决
我写了两个脚本

第一个：

$ cat runstat.ksh
host=`hostname`
tag=`date \'+%Y%m%d\'`
BaseDir=`dirname $0`
mkdir -p ${BaseDir}/log

/opt/perf/bin/glance -adviser_only -nosort -iterations 10 -j 3 -syntax ${BaseDir}/proc_IO.ksh >>${BaseDir}/log/proc_disk$tag.log 2 >&1&

第二个：
$ cat proc_IO.ksh
IF GBL_DISK_UTIL_PEAK > 80 THEN{
highestIO = 10
process loop {
IF PROC_DISK_PHYS_IO_RATE > highestIO THEN{
highestpid = proc_proc_id
highestname = proc_proc_name
highestIO = PROC_DISK_PHYS_IO_RATE
}
}
print \"--- High PHYS IO rate = \",GBL_DISK_UTIL_PEAK, \" at \",
gbl_stattime, \" ---\"print \" Process with highest IO was pid \", highestpid, \", name: \", highestname
print \" which had \", highestIO, \" physical IO of Proc\", \"utilization\"
}

运行runstat.ksh，得到的log是：
