What do you use to monitor the uptime / performance of your websites, specifically those based on a PHP/MySQL platform like Wordpress? I'm looking for something that alerts me if the site is down, or performing too slowly, and has some useful (not volumeous!) charts showing me any potential problems, and what to do about them. Thanks! ...
I am writing a script that powers on a system via network. And then i need to run a few commands on the other host. How do I know whether the system has powered on? My programming language is Perl and the target host is RHEL5. Is there any kernel interrupt or network boot information that indicates the system has powered on and the os...
Hi, I am looking for a piece of software that I can schedule to check that our web apps are up and running. I've used HP open view years ago, but remember it being quite expensive, I'm looking for something open source or cheap. So it would login in and do some simple actions maybe submit form and check for some text on screen that m...
I've written an image processing script in php which is run as a cron scheduled task (in OSX). To avoid overloading the system, the script checks the system load (using 'uptime') and only runs when load is below a predefined threshold. I've now ported this over to Windows (2003 Server) and am looking for a similar command line function ...
I have a MOSS 2007 test site, its not public facing, instead its on our intranet, I am looking for an uptime monitoring component thats free and easy to install, any suggestions? Update: I don't need graphs or anything fancy, I just need to make sure that I get a notification via email if the site goes down. ...
I run about 5 different hosted servers, through a variety of hosting providers. In the past two months, one of the servers I work on has been down twice. Both times were unexpected and fairly long (36 hours and 4 hours). The server in question is a VPS not a shared server. Given my experience with my other servers/providers (both VPS...
I have a service that accepts callbacks from a provider. Motivation: I do not want to EVER lose any callbacks (unless of course my network becomes unreachable). Let's suppose the impossible happens and my mysql server becomes unreachable for some time, I want to fallback to a secondary persistence store once I've retried several times ...
The company I work with currently has 10 windows boxes running various in house scripts, however occasionally one goes down and no one notices for periods of up to 24 hours because the data that is manufactured is only gathered on weekly intervals. Does anyone know of a management system that will notify when a box goes down and possibl...
I'm wondering i always see my load average on my computer 1.76,1.31,1.08 at the moment. but what the hell does it mean ? ...
Does anyone know of a way to programatically find the uptime of a server running Windows 2000? We have a service running on the machine written in VB.NET, that reports back to our server via a webservice. ...
I've got a Perl based FastCGI app that rarely goes down. However, when it does go down, the restart is not automatic. Restarting Apache manually always does the trick but that does address improving the uptime of the app. I'm thinking of using a cron job in conjunction with a script that uses WWW::Mechanize to periodically check on the ...
Basically, I just need a simple app that frequently pings external IP Addresses and web addresses to make sure the sites are up. Does anyone know of a good one of these? I started to make one myself, but wanted to know if someone else has already done the work. It just needs to track multiple external addresses with the status codes r...
I would like to get the system uptime from within a C application running on a linux-based system. I don't want to call uptime(1) and parse the output, I'd like to call the underlying C API I suspect exists. Anyone know if there is such a call, or does uptime(1) simply process records obtained from wtmp? ...
How do I determine the uptime on a SunOS UNIX box in seconds only? On Linux, I could simply cat /proc/uptime & take the first argument: cat /proc/uptime | awk '{print $1}' I'm trying to do the same on a SunOS UNIX box, but there is no /proc/uptime. There is an uptime command which presents the following output: $ uptime 12:13pm up ...
I'd like to trim the output from uptime 20:10 up 23 days, 3:28, 3 users, load averages: 3.84 1.06 0.64 so that it just shows: 23 days I've tried using sed, but I'm not sure it's the right tool for the job, and don't have much experience using it. How can I achieve the output I want? ...
Hi folks, is there a built-in property in any of the ASP.net classes that determines what the uptime of the webserver, where the webapplication is running on, is? These are some of the possibilities that popped into my mind: global.asax and the Application_OnStart Event. Get the timestamp and to determine the uptime, I just substract ...
I am on LAMP with Alternative PHP Cache (APC). It worked fine until yesterday when I updated the website and changed a few MySQL queries (I don't see how it would affect the APC opcode cache.) Today I see that the load has increased on the server and I see in Alternative PHP Cache, that the uptime of APC is somewhere around 15 minutes a...
I'm writting a Perl script for which I need the uptime in seconds to do some calculation, in all the machine in the shop (i.e. linux, SunOS, and AIX). I have a way to get the uptime for linux (/proc/uptime), and SunOS (kstat -p unix:0:system_misc:boot_time), thanks to an another posting on this site, but I can find a good way of getting...
I have a dynamically generated rss feed that is about 150M in size (don't ask) The problem is that it keeps crapping out sporadically and there is no way to monitor it without downloading the entire feed to get a 200 status. Pingdom times out on it and returns a 'down' error. So my question is, how do I check that this thing is up and ...
A bad side of pushing to Heroku is that I must push the code (and the server restarts automatically) before running my db migrations. This can obviously cause some 500 errors on users navigating the website having the new code without the new tables/attributes: the solution proposed by Heroku is to use the maintenance mode, but I want a...
