  • Pavel, i edited near string 337, and replase from old script who works with nmon #A# my @ps = grep {/$0(?!grep|sh -c)/} `ps -ef 2>>$error_log`; my @ps = `ps -ef 2>>$error_log|grep $0|grep -v grep|grep -v "sh -c"`; And it is work!

  • Hi, Pavel. Ok, but some correction, you use out not "free", but "cat /proc/meminfo" as: testdb3:~ # free total used free shared buffers cachedMem: 528313444 519418200 8895244 168357348 1491496 494083384-/+ buffers/cache: 23843320 504470124Swap: 12585980 0 12585980 testdb3:~ # cat /proc/meminfoMemTotal: 528313444 kBMemFree:…

  • Hi, Pavel. Why? Because can do it. You say it may do: (https://www.ibm.com/developerworks/community/forums/html/topic?id=4b21495b-cf50-47c0-9144-da7b32b8f8f5) yes, you can use only NMON (NMON is independent on the OS agent, both just use the same script/program). In fact you have 3 independent options: 1. NMON only…

  • OK. Small guide to use AD user, if you use XenServer with RBAC & AD. 1. Make changes in file /bin/xen-xapi2json.pl (see up) 2. Make AD user lpar2rrd, add his to XenServer, add him role "pool-admin" 3. Exchange SSH key from lpar2rrd user to root user on XenServer [root@stor2rrd ~]# su - lpar2rrd[lpar2rrd@stor2rrd ~]$ cd…

Go to XenServer from Lpar2RRD by SSH keys for root user: [root@stor2rrd ~]# ssh dl580-s1-l1Last login: Thu Jul 18 14:37:43 2019 from stor2rrd.domen.srv Try switch to lpar2ddr user from AD linux like: [root@dl580-s1-l1 ~]# su - lpar2rrdsu: user lpar2rrd…

    in How set host connectivity? XenServer, RBAC&AD Comment by Alex July 2019
  • Yes, as you say. If used RBAC only root user allowed to access the XenServer API. If used AD, any others users is only from external directory services (AD). So, if i make user lpar2rrd in my AD, add it in RBAC and assign role ReadOnly, this OK. But, for this user (lpar2rrd from AD) not posible manipulate RSA keys for SSH!…

  • P.S. about NMon part script of LPAR Agent. If my application on the server (SLES12) use SharedMemory, NMon too incorect display used memory. And NMon have very small parameters to right calculate UsedMemory. In my case, i need use Active parameter, as UsedMemory: ( undef, undef, $size, undef, undef, undef, $free, undef,…

  • Hi, Pavel. This topic i made when see, what LPAR Agent incorrect display used memory on my server. On my server used Oracle RDBMS without HugePages, is used SharedMemory. But current algorithm LPAR Agent do not use Shmem in calculation. Why? I search some articles, and find, what any programm calc used memory by any…

  • Why i need do this? In my server 1TiB RAM and many Oracle instances, and his can't use only 31GiB memory <span>:smile:</span> I compare output # cat /proc/meminfo; free and read article (link at top). Can you make changes in Agent Lapr2RRD in future verions?
