hobbitd status-board not available error 🔗 link

Running a new unpatched Hobbit 4.2.0 (hoping to hold for until 4.2.1)
server on Solaris 10 and getting "hobbitd status-board not available"
alerts fairly randomly (about 2 an hour). These alerts immediately
clear.
 
We also randomly get "Status not available" when clicking on a monitor,
but immediately refreshing the page clears the error. I'm thinking the
two are related. The bb-display.log is only showing the status-board
errors.
 
Any ideas?
 
Thanks,
-Rob

Solaris 10 sparc/intel  or linux ?

Not trying to start arguments, Just want to understand how others making 
their decisions ?

For me, I think Solaris 10 has following technical advantages over linux(RH) 
camp
1. Dtrace to help on problem finding.
2. Faster TCP/IP stack(rewrote and improved in Solaris 10).
3. Very rock solid stable.
4. Commercial support avaiable from Sun if needed.
5. Solarish has no  OS seat-license(RH Linux has it).

Thanks for your time

Use what you know and like.
For me, that's Linux.  I haven't used Solaris since version 9.
I've heard that 10 is good, but for me there's no reason to look back.

Hi,

Frankly I d compare that kind of question with "what is better, plasma or lcd ?".

It all depends of what you are running on your server, the number of hosts you have to check/gather reports from, how well it will integrate with your existing setup ...

I run it on Fedora Core, since my network is mostly composed of that release.
I do however use hobbit to monitor Solaris, from 8 to 10.

I prefer linux because of the thousands of packages available in standard
formats without worrying about which compiler was used to compile X. Indeed
you might say "Well hobbit compiles on my $OS", but does net-snmp? RRD tool?
perl? perl's dbi/dbh, etc?

I like debian because I write a lot of external scripts for hobbit and
debian's perl library in the native package management is incredible. Plus I
can have an identical machine configured in less than 20 minutes if I have
the output from "dpkg -l" from the old machine.

That's my 2 cents. I run 20 solaris boxen, and I try to keep as little
software on them as possible for the above reasons.

Pick whatever suits you best, I don't think there are any overwhelming
technical reasons for choosing one or the other.

At work I'm running Hobbit on Sun/SPARC hardware, with a Debian/Linux OS.
Linux was *much* better at running our old Big Brother installation*), so
that is what caused us to switch to Linux initially. When we moved to
Hobbit, I just kept linux on the boxes because it was the easiest thing
to do. (There was no compelling reason to go back to Solaris, and Linux
has all of the tools I need available, without having to download tons
of stuff from sunfreeware.com).

*) The reason why Linux is better for a BB installation is because
   the fork()/exec() system-call sequence used to launch a new program
   is incredibly slow on Solaris - that's why all of the real server
   programs for Solaris use threads. However, BB is written with shell
   scripts, so there is no way you can avoid lots of fork()/exec()
   calls with BB. And Linux just does that a lot faster than Solaris.
   At least this was true for Solaris 8, I haven't done any comparisons
   on later versions.

2. Faster TCP/IP stack(rewrote and improved in Solaris 10).

Faster than what? Solaris 9? I haven't seen sufficient benchmarking regarding Solaris 10 vs Linux 2.6 regarding TCP/IP, but you may be interested in this benchmark regarding OpenLDAP:

http://www.symas.com/benchmark-auth.shtml

Using the same hardware, application software, benchmark tools, and data, Linux 2.6 was 13-16% faster than Solaris 10.

3. Very rock solid stable.

On either platform, uptime is usually dependant on the environment (power, users), not the OS.

4. Commercial support avaiable from Sun if needed.

There are many commercial Linux vendors, and many companies offering commercial support.

5. Solarish has no  OS seat-license(RH Linux has it).

RH doesn't have licensing cost, only support cost. Solaris also has (much more expensive) support costs.

However, I don't think any of this is specific to Hobbit, and as such I don't know of this thread belongs on this list. Also, there may be a lot of other aspects to consider.

But, in our environment, we choose Linux by default for most services, Solaris only if the software is only supported on Solaris.

How do you quantify that??  I've got an old Compaq DL380 running
RedHat-7.2 that had 3 outages since it was installed in Sep'01.  The
first outage was due to moving the system, the second was due to me
fooling around with device drivers and the third time was when the
power supply died.  In between it was consistently getting 500+ days
of uptime.  Seems fairly stable to me...

I recommend FreeBSD of course ! :-))
