Monitoring

[Hoang Hung]

Hello guy:

I have  defaul timing. But indont understand >> TIMER  monitoring formula citrix

Interval: 5 second >>>>>>>>> WHAT MEAN

Response Timeout: 2 ms    >>>> WHAT MEAN

Retries: 3   >>>>>>>> WHAT MEAN

> How long waiting citrix the service to be marked down  ?.

 

Thanks all

- Interval defines how often the appliance will probe (check) the back end service, under normal operations.

- Response Timeout defines how long to wait before marking a probe as failed.

- Retries define how many times the appliance will retry connecting to the back end service which had a probe fail, before marking it as down.

 

By default a service which goes down will be marked as down after ~6-11 seconds, keeping in mind the default Response Timeout is 2 seconds, not 2 ms.

 

Minimum: 3x2 seconds (3 probes x Response Timeout)

Maximum: 5 + (3x2) seconds (Interval + (3 probes x Response Timeout))

Thanks you so much !

Hi Warnox

Why service will down after 6-11 seconds. When == 6 seconds ? When == 11 seconds? 

 

thanks

Look at the minimum and maximum I wrote in the last post. It depends on where in the ‘cycle’  the service actually goes down.

Hi Warnox

And now, I must change : After >= 30s >> server down and then How do you do ?

I think that " 

- Interval 5s

- Respone = 10s

- Retries =3 

What do you think ?

[Gregor Blaj]

That won't work because Response can't be longer than Interval (Response < Interval). The following would mark a service as failed between 30-41 seconds.

 

Interval: 11

Response: 10

Retries: 3

 

Or this for 30-36 seconds.

 

Interval: 6

Response: 5

Retries: 6

Thanks Warnox .
