apache-top provides real-time display of the active processes from a remote apache server. I’ts like the top linux command.

With apache-top you can get:

  • The active apache processes with their associated PID, the status, the seconds being active, the CPU usage, the asociated VirtualHost, the accessing ip and the request (POST or GET, the file being accessed and the used protocol)
  • The server uptime and the last time it was restarted
  • The CPU usage
  • Requests by second, Kb by second and the average Kb by request
  • Number of active and inactive processes
  • A graph with the inactive and active processes and their status




To see statistics from the webserver

apache-top -u

If for any reason we don’t have direct access to 80 port, a tunel can be createdusing ssh:

ssh -L 8080:localhost:80

And we run this command in other terminal:

apache-top -u http://localhost:8080/server-status





apache-top uses GNU/GPL License.

  1. Thanks for this project! This is exactly what I’m looking for. apachetop is good, but it is totaly useless in case you have different access log for every virutal host.

    In program help (with ?) will be great.

  2. Kepi, apache-top doesn’t use the access log to retrieve the information, so having different logs for every virtualhost doesn’t affect it

  3. fr3nd: (reply to 2)

    Yes, I know it! I talk about apachetop (the one without – :) as you said.. simmilar project with diferent approach). I like it but it is useless for me cause it depends on access logs.

    And this is why I love your’s apache-top :) It saves my live many times from time i wrote here for the first time. Thanks again.

  4. Docenta: Check you’re using apache 2.0 and try to access to that url using a “normal” browser to see if the server-status page works correctly.

  8. Maybe this is a dumb question, but is it “/server-status” dir suppose to exist? Does apache creates it when ExtendedStatus is On? Or what this folder should contain or what does apache-top is looking for in here?

    Thank you,

  9. Is there any chance of support for Apache 2.2? All I get is “ERROR parsing the data.”

  10. It works with apache 2.2 with no problem, just be sure to turn on extended status and use good url. Try it i.e. with links

  11. We have the same problem as DOCENTA. Yes we using Apache 2 and yes URL in browser is working fine.

  12. “ERROR parsing the data. Please, make sure you are alowed to read the server-status page and you have ExtendedStatus flag activated”
    same here with apache 2.2.
    any solution?

  13. Thanks for this project its great..

    What we need for update is –

    spacebar refresh

    Also, is their a active thread or mailing list for people working on this project?

  14. @shawn: Sure you can! Just let me know the url where you publish it when it’s online so I can update this page.


  15. @shawn: It would be interesting to also code it for Lighttpd and nginx support. I can help you with testing on them, if necessary.

  16. Better finding this later rather than never… lol

    It’s extactly what I’ve been looking for a while now!

    Cheers! :)

  17. ERROR parsing the data. Please, make sure you are alowed to read the server-status page and you have ExtendedStatus flag activated

    I was getting this error to, then I setted up apache location for server-status to allow from

    Allow from

    and because I setted it up as password protected area I had to add username and password to the url

    python apache-top.py -u http://username:pass@localhost/server-status

  18. Dear Carles Amigó (fr3nd), Thank you for your script and It helps me solved many technic problems.

    I’ll ask your permission to add some functions to your excellent work as follows, I hope that it doesn’t bother you here:


    I found one major defect in the old versions.
    The Monitoring process is constantly interrupted when the server is busy, or
    some apache process is interrupted by the system control. One must constantly
    launch the apache-top.py.
    As the modified script does a good job for me, I would like to share this with
    other users.
    Compared to the above two versions, I bring these improvements:

    Added -d time command option, you can input directly the interval delay for status refreshing.
    for the coherence, I’ve replaced the s interactive command by d, similar to the new apachetop command, to change the interval delay.
    Add h interactive command in order to show a help screen, just as does in top command.
    Replaced urllib.urlopen() by urllib2.urlopen(), in order to specify URL opening timeout,
    avoiding the infinite looping when the user type a nonexistent, or temporarily unavailable server URL.
    Modified the class method ApacheStatusParser.handle_entityref(), so in screen mode,
    URL arguments sepatator is correctly shown as & but not & as before, ie,
    but not as http://www.domain.tld/mydancer.php?name=Carolina&sex=f.
    Bypassing the HTML parsing error. Even for a valid URL, an error apache server output will no more interrupt the
    monitoring, with the error:
    ERROR parsing the data. Please, make sure you are alowed to read the server-status page and you have ExtendedStatus flag activated.
    This point is useful for a very busy web server, as http://www.domain.tld/server-status can
    often output incomplete HTML string, sometimes it may be blocked by other processes so HTMLParser cannot parse correctly in time.
    This aborted very often the monitoring process. With the modification, the monitor will simply pass this turn.
    It can work for days and days only if you type the interactive command q to quit.

  19. Dear Carles,

    I found that you are the busy man who made mysqldump, I would not bother you and for the simplicity, send the email to the generic email account on your site webmaster at fr3nd.net with apache-top.py joined.
    Please tell me if you don’t receive it.

    The modified Apache-top.py uses 4 spaces indentation.

    I’ve found no way to upload on your page: https://github.com/fr3nd/apache-top

    Please merge my work with yours if you check good.



  20. Great software. I have it running and I am trying to find the cause of my server getting bombarded offline. This usually happens after a few minutes of maybe 1500 packets/sec traffic. Now I don’t want to be staring at my screen all day and wait for it to happen again. Is there a possibility to save everything to a log file?

    Keep up the good work!



  21. Ok thanks! I will look into that. I allready was able to find out what caused the load on my server and managed to get rid of it. Without apache-top that would have been a real problem.
