Help Needed !basic Monitoring Unix Servers

[ksudheer253]

We are trying to setup monitoring for all our web servers and application servers which are running on UNIX. Trying to implement only the basic monitoring but not their performance,like if we try to hit the website and if there is an outage on webserver or on back end servers there should be some alerts coming to the team who are monitoring it. Is there any scripts that would run and throws alert if there is any outage?

Suggestions would be appreciated. Thanks

Ya guruji..server down ayi napudu ..edo oka kind of alert raavali,either mail or sms...

Tools kana...scripts thoney alerts kavali antunaru,,,

then write ur own... every environment has its own monitoring tools & scripts

[maverick23]

Usually monitoring ke ...You can write shell script.....Like CPU,Memory,disk space,memory leak ilanti parameters ke vati threshold levels datite the admin can get email alert.......If there are more systems to monitor, You can also implement using "Splunk" software......which is cool GUI interface.....But license ke it will cost!!! It really depends on number of servers you want to monitor!!

We have around 14 linux servers. Ya splunk aithey licence undali...but i am trying to check on website for sample codes...does anyone know any websites where i could get sample scripts for alert monitoring.

Thanks

you want tot write script to monitor ??

then you can use shell script to monitor the process (but not efficient) if any application dies it will mail the content


but how big is ur application (client base) down time etc....also need to consider( some times application runs but memory heap will be hig)

some times certain ports will not close...or any other reason ...applications will run but no request is processed so

what exactly u r looking for
