Dell Monitoring OMSA Monitoring

The nagiso  client requires that the  OMSA (openmanage server administrator)  nagios Client installation must be installed on the Dell server omsa  (Refer to http://linux.dell.com/repo/hardware/OMSA_7.4.0/)  1, adding Dell's Yum library   (  access to  http:// linux.dell.com/repo/hardware  View Latest version  )  wget -q -o - http://linux.dell.com/ REPO/HARDWARE/OMSA_7.4.0/BOOTSTRAP.CGI | BASH 2, installation srvadmin yum install  Srvadmin-all -y 3, start srvadmin/opt/dell/srvadmin/sbin/srvadmin-services.sh startnagios  server configuration  1, Dell official Omsa monitoring script download (download to nagios  server  /usr/local/nagios/libexec, and assign Nagios Execute permissions)  wget   http://folk.uio.no/trondham/software/check_openmanage-3.7.11/check_openmanage   also, due to the Check_ OpenManage is a Perl script, so Perl interpreter   need to install  PERL-NET-SNMPYUM INSTALL PERL-NET-SNMP   2, The following is a manual execution of the script to get the hardware status   #电压./check_openmanage -h 192.168.1.100  --only voltagevoltage  ok - 20 voltage probes checked  #cpu./check_openmanage -h 192.168.1.100  --only cpuprocessors  OK - 1 processors checked  #风扇转速./check_openmanage -h 192.168.1.100   --only fansfans ok - 12 fan probes checked# storage./check_openmanage  -H 192.168.1.100  --only storageSTORAGE OK - 3 physical  drives, 1 logical drives  #内存./check_openmanage -h 192.168.1.100  -- only memorymemory ok - 2 memory modules, 32768 mb total  memory  #电池./check_openmanage -h 192.168.1.100  --only batteriesbatteries ok  - 1 batteries checked check_openmanage  script for more detailed usage please refer to: http://folk.uio.no/trondham/ software/check_openmanage.html if the above no error, it can be configured to nagios , the configuration method online more, here is not much to say # uninstall openmanage server  Administratoryum erase $ (Rpm -qa | grep srvadmin) 

Fault Handling

1. When the system log appears  Server Administrator  (shared library): data engine eventid:  0  a semaphore set has to be created but the system  limit for the maximum number of semaphore sets has been  exceeded   When this thing comes up, it means that your surveillance is no longer available.   is probably meant to say: Data engine failed to open successfully due to the maximum number of signals in the system.   This requires modifying the system kernel's settings for  semaphore sets .

We'll use our own methods to monitor the state of the machine.
