Hello,

Unfortunately, I have :Status not available.

for

But the following works fine:

On your bbdisplay it is probably the very first line item.  For
example it says bbtest on this page:

Hello,

Could you please tell me where I can get this info?

Thanks in advance for your help.

Well instead of guessing - look at bbtest and see what the DNS test
times are.  If you can, share the entire output.

Hello,

If I do, from the hobbit server:
nslookup xxx.unige.ch ip_address_dns
respond very fast.

In resolv.conf, the dns in the first line is our authoritative name
server.

Therefore it does not seems to be the dns time.

I want to say that Xymon doesn't use cache, issuing a query upon every
new host, but I am not certain.

Hello,

As I have already said, this would be dur to the dns,
I would have had the pb with wget too wouldn't I?

I am wondering if you have a DNS issue causing latency.  Just a
thought.

Have you done a trace route from the Xymon server? Maybe that would
show
you something? Sorry just a suggestion from the top of my head.

Subject: [xymon] Wrong (or badly interpreted) http response time
with
hobbit 4.2.0

Hello,

I have monitored machines that are reporting around 3.5 seconds
for the HTTP response time during the whole day (curve flat).

If I do wgets, from the Solaris machine where hobbit server is
installed,
I get response times that is lower than 100 ms.

Our old BB server reports response times that are also lower than
100
ms.

Would you know why my hobbit monitor report such high response
times?

Thanks in advance for your answer.
