A lot of time, when I do my checks, I'm not nearly as interested in the value of a check as in the change in the value since the last check. This is a good example. Another item I monitor is changes in the SNMP Interface error counters. For example, if I get more than 5 errors/second, I need to send out an alert. Finally, I have the same issue monitoring SNMP Interface statuses. But, Nagios has no feature to remember data between invocations of the checks. So, I end up storing this data in temporary files. If there was a facility to provide some information back to Nagios, and retrieve it on the next one, that would be wonderful.</FONT></SPAN></DIV> <DIV align=left><SPAN class=584225518-17102006><FONT face=Arial color=#0000ff size=2></FONT></SPAN> </DIV> <DIV align=left><SPAN class=584225518-17102006><FONT face=Arial color=#0000ff size=2>Jason</FONT></SPAN></DIV> <DIV align=left><SPAN class=584225518-17102006><FONT face=Arial color=#0000ff size=2></FONT></SPAN> </DIV> <DIV align=left> <HR> </DIV> <DIV align=left><FONT face=Tahoma size=2><B>From:</B> nagios-users-bounces@lists.sourceforge.net [mailto:nagios-users-bounces@lists.sourceforge.net] <B>On Behalf Of </B>Andrew Cruse<BR><B>Sent:</B> Tuesday, October 17, 2006 1:52 PM<BR><B>To:</B> 'Maxwell,Brady'; nagios-users@lists.sourceforge.net<BR><B>Subject:</B> Re: [Nagios-users] checking a counter on a website<BR></FONT><BR></DIV> <DIV></DIV> <DIV class=Section1> <P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">I would just write a quick script that grabs the value on the counter, then grabs the value again and subtracts the first from the second. Publish that value out via SNMP and then just use check_snmp to verify that the value is >=1. People with more programming skills than I would probably just write one plugin to do it all.</SPAN></FONT></P> <P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial"></SPAN></FONT> </P> <P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">Andrew</SPAN></FONT></P> <P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial"></SPAN></FONT> </P> <DIV> <DIV class=MsoNormal style="TEXT-ALIGN: center" align=center><FONT face="Times New Roman" size=3><SPAN style="FONT-SIZE: 12pt"> <HR align=center size=2> </SPAN></FONT></DIV> <P class=MsoNormal><B><FONT face=Tahoma size=2><SPAN style="FONT-WEIGHT: bold; FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">From:</SPAN></FONT></B><FONT face=Tahoma size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma"> nagios-users-bounces@lists.sourceforge.net [mailto:nagios-users-bounces@lists.sourceforge.net] <B><SPAN style="FONT-WEIGHT: bold">On Behalf Of </SPAN></B>Maxwell,Brady<BR><B><SPAN style="FONT-WEIGHT: bold">Sent:</SPAN></B> Tuesday, October 17, 2006 2:45 PM<BR><B><SPAN style="FONT-WEIGHT: bold">To:</SPAN></B> nagios-users@lists.sourceforge.net<BR><B><SPAN style="FONT-WEIGHT: bold">Subject:</SPAN></B> [Nagios-users] checking a counter on a website</SPAN></FONT></P></DIV> <P class=MsoNormal><FONT face="Times New Roman" size=3><SPAN style="FONT-SIZE: 12pt"></SPAN></FONT> </P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Anyone ever tried to check a websites hit counter and return a warning if the hit counter has not incremented since the previous check? </SPAN></FONT></P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"></SPAN></FONT> </P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"></SPAN></FONT> </P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Brady Maxwell</SPAN></FONT></P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Systems Engineer</SPAN></FONT></P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Online Computer Library Center, Inc.</SPAN></FONT></P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">614.764.6133 | maxwellb@oclc.org</SPAN></FONT></P> <P class=MsoNormal><FONT face="Times New Roman" size=3><SPAN style="FONT-SIZE: 12pt"></SPAN></FONT> </P></DIV> <TABLE> <TBODY> <TR> <TD bgcolor=#ffffff><FONT color=#000000><BR><FONT face=arial size=1>This message (including any attachments) may contain confidential or otherwise privileged information and is intended only for the individual(s) to which it is addressed.
