SQL Server checks CPU usage. At noon today, a friend asked me to help him check the database. The operating system is Windows2008R2, the database is SQL2008R264-bit 64 GB memory, and the 16-core CPU hardware configuration is still relatively high, he said that the server is running Kingdee K3 software, and there are mu

2. Create a script file
# vim /home/htdocs/monitor/mrtg/sh/mrtg.memory
Add the following script:
#!/bin/bash# run this script to check the mem usage.totalmem=`/usr/bin/free |grep Mem |awk '{print $2}'`usedmem=`/usr/bin/free |grep Mem |awk '{print $3}'`UPtime=`/usr/bin/uptime | awk '{print $3""$4""$5}'`echo $totalmemecho $usedmemecho $UPtimeecho localhost
3. grant it the operation permission.
# chmod +x /home/htdocs/monitor/mrtg/sh/mrtg.memory
