    Hi,

    I am trying to gather performance metrics on a UNIX server (Solaris 10) but I get the error below when I open my scenario in the Loadrunner Controller. The rstatd daemon is running on the UNIX server. I can ping the server. Can anyone shed any light on what how I can resolve the issue? <font color="blue"> </font>

    Monitor name :UNIX Resources. Cannot initialize the monitoring on &lt;Server IP Address&gt;. Error while creating the RPC client. Ensure that the machine can be connected and that it runs the rstat daemon (use rpcinfo utility for this verification).

    Detailed error: RPC: Failed to create RPC client.
    RPC-TCP: Failed to establish RPC server address.
    RPC-TCP: Failed to communicate with the portmapper on host '10.16.215.198'.
    RPC: RPC call failed.
    RPC: Server did not allow operation due to unknown reasons. (entry point: CFactory::Initialize). [MsgId: MMSG-47190]

    Hi Sinead

    Does the 'ping' returns positive results for the UNIX machine?

    Also for RPC calls appropriate Port has to be enabled. Checkout the same with your network administrator.

    Verify for Firewall status as well.

    Re: Collect Unix Metrics

    Rstatd is old technology. Beginning with LoadRunner 8.0 a 500 point version of SitsScope ships with LoadRunner explicitly for monitoring use. Using SiteScope is the recommended model for full resource collection off of 'NIX style hosts.

    Grab that SiteScope disc which came with your version of 9.5, install it and you will have a much more robust mechanism for collecting the UNIX stats. Advantages:
    (1) Uses no agent. Uses SSH/Telnet to login under the covers and run commands, such as VMSTAT, to collect appropriate metrics on the system
    (2) Richer data sets than what is allowed on RSTAT
    (3) No arguing with your system admin to deploy RSTAT depsite company policies (due to security issues with the service)

    If you wish to go the native controller route and not deploy SiteScope then you also have SNMP available as an option.

    Re: Collect Unix Metrics

    Hi,

    I'm trying to setup the proper monitors in sitescope but I'm not sure what values to select in the "Unix Resources" monitor for objects, instances &amp; counters. Can anyone recommend the best values to select to monitor Disk I/O &amp; memory? The sitescope doco doesn't provide detailed information.

    Re: Collect Unix Metrics

    What you need to monitor comes from your experience in system engineering as well as recommendations from platform owners on what they observe to identify a resource constraint. SiteScope docs will direct you "How" but not "what."

    Re: Collect Unix Metrics

    The downside of using SiteScope over RStatd is how often you can receive the metrics. SiteScope is limited to about every 15 seconds.. but we have found you need to increase that time on a busy server or the SiteScope monitor might fail to return anything. RStatd can return data much quicker.

    Re: Collect Unix Metrics

    This then is the trade off between detail and time. Smaller time interval, less detail (rstatd). Shawn, you might consider the SNMP monitor which can provide similar level of detail as SiteScope but takes quite a bit more to set it up correctly.
