www site monitor
Hi list, I must monitor remote site to check that it works. I refresh this site from time to time in web browser. Can I automate this process? I search for service which: - monitors *remote* WWW site (via http request) - when remote site doesn't respond for example 5 minutes it notify some person (via e-mail or SMS). Is that service available in Debian repository? Or is there any commercial product which do that?

I've made those things happen on my nets with both Monit and Nagios (I think; I never can remember whether it's Nessus or Nagios), but Monit is a whole lot easier to get going (the other one is vastly more flexible, though). -- Glenn English -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Re: www site monitor
Hi! I think, you could write a script for this. Using perhaps ping, to just see, if the server responds or wget to download a certain file. I'm not sure though about their timeouts. I think you can set a tieout with wget. Then you could use mail to send an e-mail. I suppose, tat there might be a more comfotable way with more GUI stuff, but that would do the trick. I've seen: ping -W timeout_in_secs server This will only timeout after timeout_secs, if no response is received. The line to send mail would be: cat file | nail -s subject -r from@host to@host That should do.

Best regards As has already been suggested - mon will do the job *if* all you want to do is check to see the server is up Nagios will do more, though it's probably overkill. It's possible that just knowing the server is serving something* may not be what you're after... If you want to check that the site is functioning[*1] as expected then you have several, scripted, options depending on how deep you want to test (any modifications, file size, site wide tests). Use wget[*2] Use curl and just compare filesize against an expected value - or use pgp to check for any changes. There's a number of gratis webservices like pingdom which will confirm the site is up (and maybe serving fake antivirus or 503s). [*1] you may wish to test ports 25, 53, 80 and 443 (and others). My personal preference is to run check on the server, then send (tiny) email status reports to a remote client. The absence of a regular report indicates a serious problem. Changes to the subject line indicate various errors. The remote client box can then alert your mobile with an email if needed. [*2] eg.:- #!/bin/bash WGET=/usr/bin/wget $WGET -q --tries=20 --timeout=5 $site2test -O /tmp/site.test /dev/null if [ ! -s /tmp/site.test ];then echo crapulence else echo go back to sleep fi ===4cron== * * * * * /usr/bin/wget $site2test --timeout 20 -O - 2/dev/null | grep go back to sleep || echo crapulence | /usr/bin/mail -v -s crapulence d.d...@wonderland.mil == Kind regards -- Iceweasel/Firefox extensions for finding answers to Debian questions:- https://addons.mozilla.org/en-US/firefox/collections/Scott_Ferguson/debian/ -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

assume you have a local working smtp server, let's check if debian is
online by running following script from cron.
---Begin--
#!/usr/bin/env python
import urllib2
import cookielib
URL = 'http://www.debian.org/'
def browser():
cj = cookielib.CookieJar()
cookie_support = urllib2.HTTPCookieProcessor(cj)
opener = urllib2.build_opener(urllib2.HTTPHandler, cookie_support)
return opener
def sendmail(subject, msgbody):
'''send mail to gmail via a working local exim4'''
import smtplib
from email.mime.text import MIMEText
msg = MIMEText(msgbody)
from_addr = 'my_address'
dest_addr = 'man_on_duty'
msg['Subject'] = subject
msg['From'] = from_addr
msg['To'] = dest_addr
msg.set_charset('utf8')
s_obj = smtplib.SMTP('localhost')
s_obj.sendmail(from_addr, dest_addr, msg.as_string())
print 'Successfully sent mail to {0}'.format(dest_addr)
s_obj.quit()
def main(url):
brs = browser()
try:
site = brs.open(url)
except urllib2.URLError:
sendmail('datacenter on fire?')
except urllib2.HTTPError:
sendmail('or under water')
if __name__ == __main__:
main(URL)
