Any tools to check/monitor server uptime?

hi, can anyone introduce a tool/utiities to monitor the uptme of a web server?

Thanks.

 

I suppose such tools exist, but I'm curious how such a tool would work without constantly hitting a website and thus slowing it down.

 

Hi.

Do you mean software to install at your server(s)/PC, or online uptime monitoring services?

 

Hi.

One HTTP (for example) request per 1+ minute(s) should not cause to any noticable slowdowns for your site/server.

 

Hi,

I let the server do the uptime logging into a file, which I load down occasionly.
The skript (linux) looks something like this:

#!/bin/bash
while [ 1 ]
  do
    /usr/bin/uptime >>uptime.log
    sleep 60
  done
exit 0

Code (markup):

You also see the load average with such a skript, but you don't know whether the webserver is up.

To know wether the server is up you need to use "external" monitoring tool.

It can be some monitoring software on your local PC, but then you would need 24/7 PC up and 24/7 reliable internet connection.

Or it can be a web-based monitoring service which will log your server outages, alert you about the downtimes etc.

 

I used alertra.com a few years back and also internetseer (which wasnt that good... partly because they monitored my site and spammed me with out me requesting to be monitored). Those can get a little pricey but if your site is making money then it might be worth checking them out.

 

Hi.

A lot of uptime monitoring systems provide free solutions along with the paid ones . If you don't need short uptime check periods and/or advanced features then such free solution should be comfortable for you.

 

Can anyone name a good free remote solution? And, how often do they check? At least once a minute would be ideal I suppose.

 

We can suggest one at least

HostTracker offers a check every minute - and I don't believe they charge.

 

There's a monitoring site called Observe Point. I use it and enjoy it. The reports are easy to read and you don't have to have a degree in computer programming to use it. I chose observe Point because it's also used by companies like; Omniture, ROI Rocket, Ward Media Inc., Efamily Network, and others. Whenever my website is down it will call, text, and E-mail me. It will cover you're Uptime, Transactions, pixel tracking, and site audits. It's a great web server/website monitoring helper.

 

there are many paid sites which monitor your server when your server was down they will contact you and alert you by e-mail or sms

 

I use Web CEO.

 

Pindom.com, host-tracker.com, hyperspin.com, alertra.com - all solid services.

 

BinaryCanary is another service. They have a free service that you can use to test the service.

the one i use is http://www.hyperspin.com, you can create a public profile so you can show your uptime to others e.g. heres mine http://www.hyperspin.com/publicreport/4723/60158

 

I use Host-Tracker.

 

I'm not sure about this but I know you can find online services like this which provides system administration like supportpro.com

 

[FONT="myriad pro,helvetica,Arial"]I'm not sure if the OP is still around, but you can also try Alertable.

It's free and sends you a direct message on Twitter when your site goes down.[/FONT]
