[RADIATOR] "Wellness" metric

[Hugh Irvine]

Hello Dominic -

The best way to see what is happening is to use a trace 4 debug with  
LogMicroseconds:

......

# requires Time-Hires from CPAN

<Log FILE>
	LogMicroseconds
	Trace 4
	Filename %L/microseconds-log-%Y-%m-%d
</Log>

......

This will include a six digit microseconds offset in each DEBUG  
timestamp so you can see exactly how long each processing step is  
taking.

Almost all cases of slow response I have observed are due to slow  
database responses (SQL, LDAP, AD, .....).

And as mentioned already, it is handy to have a Wireshark (ethereal)  
packet capture for comparison purposes.

hope that helps

regards

Hugh

NB:

Have you read the reference manual ("doc/ref.html")?
Have you searched the mailing list archive (www.open.com.au/archives/radiator 
)?
Have you had a quick look on Google (www.google.com)?
Have you included a copy of your configuration file (no secrets),
together with a trace 4 debug showing what is happening?
Have you checked the RadiusExpert wiki:
