I am using hobbitping and I am getting 43 seconds for 833 hosts pings.

PING test completed (833 hosts) 1157070413.072972
42.444355

Is there a way to improve number if parallel pings by hobbitping ?

Hmm, Execuse the bad sentence, I was attempting to type following,

Is there a way to increase numbers of parallel pings by hobbitping ?

tj

my test hobbit server looks very low on load avgerage.

thanks for your pointer.

Network tests rarely put much load on your box, they spend most of their time waiting for the remote server to respond.

You can probably increase the max. packets/second from the default (50) to e.g. 200 or 500. The risk in doing that is that you might overload some of the network components along the way to the server, and ICMP packets are among the first to be discarded if a router sees more traffic than it can handle. So there's a higher risk of getting false alerts the higher you go with the packet rate.

I haven't try max packet/second yet but I increase the the number concurreny of pings from default 250 to 1000 and I am seeing 10 seconds improvement(not bad).

bash-3.00$ grep concurrency hobbitlaunch.cfg CMD bbtest-net --report --ping --checkresponse --dnslog=$BBSERVERLOGS/dns.log --concurrency=1000 bash-3.00$

Looks like a ext module need to be writting for hobbit, and I propose using smf instead svcs(windows used it already).

Regarding point one, an external script seems like the best idea rather than Henrik maintaining Solaris specific functions in the hobbit client (unless his to do list is looking a bit thin ;-) )

However I disagree with your second point - if the "svcs" column indicates service status on Windows, why can't it indicate services on Solaris too? You're hardly likely to run both Sun and Windows services on the same (virtual) host, and it keeps the column numbers down on pages that might show both types of server.

Hello -

I'm running into an issue where I need to monitor the individual services ( svcs -a ) instead of the processes (ps -ef) on multiple Solaris 10 clients. I didn't see anything in the man pages about it (although I may have missed it) so I was wondering if anyone has been able to set Hobbit up to do so?

Sample output from svcs -a

$ svcs -a |head -20 STATE STIME FMRI legacy_run Jul_28 lrc:/etc/rcS_d/S00umask_sh legacy_run Jul_28 lrc:/etc/rcS_d/S29wrsmcfg legacy_run Jul_28 lrc:/etc/rcS_d/S51installupdates disabled Jul_28 svc:/system/sysidtool:net disabled Jul_28 svc:/system/sysidtool:system disabled Jul_28 svc:/network/rpc/keyserv:default disabled Jul_28 svc:/network/rpc/nisplus:default disabled Jul_28 svc:/network/nis/server:default online Jul_28 svc:/milestone/multi-user-server:default online Jul_28 svc:/system/zones:default online Aug_15 svc:/application/hobbit:default

I need to be able to alarm if zones goes offline or if nisplus goes online (for example)...

Thanks!

So if you click on svcs column title link on a hobbit page to find out the definition of svcs, which url it should link to :)

"The svcs column shows the status of select system services that are expected to run on the system"

Sounds generic enough for me! Of course, I'm not planning on submitting the ext script myself any time soon, so I'll leave it up to "someone else" to decide.

And BTW... reading the documentation? What were you thinking!

I think it is best to have unique column name. it Solaris 10's case it has smf to fall back on, giving up svcs to windows camp looks ok me.

I like to display hobbit configuration file also, where can I find this script ?

It's my highly guarded secret intellectual property :-)

exit 0

The "safequery" utility just scans the QUERY_STRING environment and if it only contains characters that are "safe" in a shell script, it prints out the QUERY_STRING value. This is something I wrote years ago to make this kind of quick-and-dirty CGI scripts safer to use.

#include <stdio.h> #include <string.h> #include <stdlib.h>

char *safechars="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.-_+?~=";

int main(int argc, char *argv[]) { unsigned char *querystring; unsigned char *p;

querystring = getenv("QUERY_STRING");
if (!querystring) {
   return 0;
};


for (p=querystring; (*p); p++) {
  if (!strchr(safechars, *p)) {
     return 1;
  }
}

printf("%s\n", querystring);
return 0;

}

Thanks for the feedback.. Looks like I have a bit of scripting to do.....
