[ERR 500] Caution ?
What percent of website 500 errors would be a warning to system load?

Example:
A well past month had 50 million hits, 4 million pages and generated 6
thousand 500 errors.
A more recent month have 88 million hits, 8 million page views and 55
thousand 500 errors.

In this case there was close to doube traffic but a huge jump in 500 errors.
Thoughts ?


Thanks

How many web servers do you have? Sounds like you better add more servers or
more horsepower.

I got this from another user at one time:

You can use the 'top' utility for nice reporting on CPU idle, free
memory, etc. When the CPU idle is commonly below 20-30 percent it's time
to redistribute the load.

I agree ...

But I am wondering if anyone has documented or set guidelines for
something like this ....

Consider the harder problem ...

... Explaining to non-computer people that this is a "bad-thing"

Any other resources out there ?

Thanks

You need to start be examining the server's error log to see what
explanations it gives for the errors.

hmm... it'd be 'coz Perl is executed every time the page is loaded so
perl may be in memory 100 times at once. Try using PHP as an apache
module wh will reduce yours 500s.
