I am trying to run the Grinder and Console on a single Solaris 8 machine connected to a LAN. The problem is that the Grinder does not receive any messages from the Console. I have used the same software and properties file on a corporate network and found that everything works OK. So this is really more of a question about multicast on Solaris as opposed to Grinder; I just thought many people will be on Solaris and one may have a solution. I am using address 224.0.0.0 as this seems to be documented everywhere as the Solaris multicast address. Any ideas would be appreciated. Thanks Ed |

Normally multicast "just works", which makes it very frustrating when it doesn't. Can you figure out whether multicast is enabled on the interface your using using ifconfig? - Phil |

Ed, I have run into this before and one important fact I learned from Phil's book ("J2EE Performance Testing") is that you don't have to have the console running in order for Grinder to generate load tests. This is particularly important for us since we're often trying to resolve some bottleneck and we're more interested in the load itself than in the performance results. (I believe the results are still written to disk at completion of the test even in the absence of the console.) Here's a relevant fragment from a properties file that will run without the console (notice the commented lines): grinder.processes=1 grinder.threads=1 grinder.cycles=1 grinder.receiveConsoleSignals=false #grinder.grinderAddress=228.1.1.1 #grinder.grinderPort=1234 grinder.reportToConsole=false grinder.consoleAddress=localhost grinder.consolePort=6372 Hope this helps, Tom --- Philip Aston <pa...@be...> wrote: > > Edward Barrett writes: > > I am trying to run the Grinder and Console on a > single Solaris 8 machine > > connected to a LAN. > > > > The problem is that the Grinder does not receive > any messages from the > > Console.
