I am trying to monitor the ambient on an IBM RSA II card with the OID: .1.3.6.1.4.1.2.3.51.1.2.1.5.1 The return answer is an string with this definition from IBM MIB for this RSA II card System's ambient temperature in degrees centigrade(C). This is surrounding temperature where the system is installed. An octet string expressed as 'sddd.dd Centigrade' where: s is the sign ('-' for negative or blank space for positive) d is a decimal digit or blank space for a leading zero.. The string 'Not Readable!' indicates that the given monitor is not supported on this system. so I get the result " 20.00 Centigrade" right now but MRTG don't seem to handle it ? (Nagios handles the return string perfect that is running om the same host as MRTG (Linux).) My cfg looks like # rsa-esx-shamn01 - temp - io YLegend[rsa-esx-shamn01-temp-io]: temperature in Celsius Options[rsa-esx-shamn01-temp-io]: growright,gauge,nopercent,absolute Target[rsa-esx-shamn01-temp-io]: .1.3.6.1.4.1.2.3.51.1.2.1.5.1&.1.3.6.1.4.1.2.3.51.1.2.1.5.1:public@rsa-esx-shamn01 MaxBytes[rsa-esx-shamn01-temp-io]: 45 Unscaled[rsa-esx-shamn01-temp-io]: dwmy Title[rsa-esx-shamn01-temp-io]: rsa-esx-shamn01 - ioBoard Temp ShortLegend[rsa-esx-shamn01-temp-io]: C Legend1[rsa-esx-shamn01-temp-io]: in next minute Legend2[rsa-esx-shamn01-temp-io]: in next minute Legend3[rsa-esx-shamn01-temp-io]: Maximal 5 Minute Legend4[rsa-esx-shamn01-temp-io]: Maximal 5 Minute LegendI[rsa-esx-shamn01-temp-io]: &nbsp; LegendO[rsa-esx-shamn01-temp-io]: &nbsp; PageTop[rsa-esx-shamn01-temp-io]: <H1>rsa-esx-shamn01 - ioBoard temp</H1> The log says: 2010-07-30 12:05:02 -- SNMPGET Problem for .1.3.6.1.4.1.2.3.51.1.2.1.5.1 .1.3.6.1.4.1.2.3.51.1.2.1.5.1 sysUptime sysName on public@rsa-esx-shamn01::::::v4only at /usr/local/mrtg-2/bin/mrtg line 2202 2010-07-30 12:05:28 -- 2010-07-30 12:05:28: ERROR: Target[rsa-esx-shamn01-temp-io][_IN_] ' $target->[0]{$mode} ' did not eval into defined data 2010-07-30 12:05:28 -- 2010-07-30 12:05:28: ERROR: Target[rsa-esx-shamn01-temp-io][_OUT_] ' $target->[0]{$mode} ' did not eval into defined data I am using MRTG version 2.16.2 Can this be handlen within mrtg scripts or do I need an perl script to handle this string ?. Does anyone have an solution for my issue ?

The string 'Not Readable!' indicates that the given monitor is not supported on this system. The usual idiom from the device manufacturers is to record the value in integer centi-degrees, then you would use a factor[] to scale it properly. But a string is not expected... Quote: so I get the result " 20.00 Centigrade" right now but MRTG don't seem to handle it ? Correct, mrtg expects a number. You will need to use a "conversion code" script to make this work. It's still a perl snippet, but the interfaces are pretty well defined. See the docs on this. A sample perl sub to perform this might be: sub tempString { #grab 1st argument as the string to convert my $String = shift; #look for optional negative sign followed by 4 to 6 digits or decimal points $String =~ /(-?[\.\d]{4,6})/; my $val = $1; #recast as a number $val +=0; #Convert to an integer $val *= 100; $val = int($val); #return the value: return $val; } -- Daniel J McDonald, CCIE # 2495, CISSP # 78281 _______________________________________________ mrtg mailing list mrtg@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/mrtg Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         BlueQuartz.US Forum Index -> MRTG Users All times are GMT - 5 Hours Page 1 of 1   Jump to: Select a forum General Information----------------Terms and Conditions of UseGeneral InformationGeneral Announcements Listserver mirrors----------------About the Listserver mirrorsBlueOnyxBlueQuartzFedora UsersCentOS Discussions and InformationCentOS AnnounceCentOS DevelopersClamAV UsersMailScanner DiscussionsMajordomo UsersMRTG UsersMunin UsersOpenSSL UsersOpenSSL AnnounceOpenSSL DevelopersOpenSSL CVSPHP General UsersphpMyAdmin UsersphpMyAdmin DevelopersRuby on Rails GeneralRuby on Rails CoreSpamassassin UsersSpamassassin DevelopersYum UsersYum Development Suggestion Box----------------Suggestions for this site  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2005 phpBB Group
