how can i graph my temperature

[lisa_parma]

hi,all
sory if my English very bad
I’m beginner in using cacti

I have some problem in using cacti…

I’m using cacti to monitoring my netguardian temperature



when i use snmpwalk for the OID temperature, i get this value
.1.3.6.1.4.1.2682.1.2.2.1.5.99.1.10 = STRING: "........ 21.5035"




the real temperature is 21.5035 celsius
the problem here is when i run my snmpwalk for the OID temperature
i got value "........ 21.5035"
i dont understand, how can i get the real temperature value< 21.5035 not "........ 21.5035">

should I modify cacti’source code??
can you tell me where part of cacti's source code that I should modify???
cause I’m beginner too in using PHP

please help me
thx b4:)

try

Code: Select all

snmpget -Ovq -c<community> -v<version> host IOD

Should get results like this:

Code: Select all

snmpget -Ovq localhost laLoad.1
0.12

instead of this:

Code: Select all

snmpget localhost laLoad.1
UCD-SNMP-MIB::laLoad.1 = STRING: 0.03

i have try to do this

snmpget -v 1 -c public 10.2.4.66 .1.3.6.1.4.1.2682.1.2.2.1.5.99.1.10

the result is:
SNMPv2-SMII::enterprises.2682.1.2.2.1.5.99.1.10= STRING "........ 20.0425"

the real temperature value is just 20.0425

that i should modify cacti's source code?

this has nothing to do with cacti: you're just using snmpget.

try

Code: Select all

snmpget -Oqn -v1 -cpublic 10.2.4.66 .1.3.6.1.4.1.2682.1.2.2.1.5.99.1.10

That should just return the numeric value you want. The Oqn options trim the results so you don't get extra stuff.

From there, you should be able to setup Cacti to query a single OID using that value (1.3.6.1.4.1.2682.1.2.2.1.5.99.1.10).

i have try do this

snmpget -Oqn -c public -v 1 10.2.4.66 .1.3.6.1.4.1.2682.1.2.2.1.5.99.1.10
result:
.1.3.6.1.4.1.2682.1.2.2.1.5.99.1.10 "........ 20.1100"

and try this
snmpget -Ovq -c public -v 1 10.2.4.66 .1.3.6.1.4.1.2682.1.2.2.1.5.99.1.10
result:
"........ 20.0650"

and i have make my snmp_query in xml,i attach in NGD_temp3.xml
i have add that xml in cacati<data_query>

rrd file have generate but no data i have found

this is the return value in cacti log:
02/01/2006 01:31:02 PM - CMDPHP: Poller[0] Host[2] DS[35] WARNING: Result from CMD not valid. Partial Result:

Your snmp agent is returning bogus data from the query. If you can't get the vendor to correct their code, you best bet would be to write a PHP Script Server script to trim the non alpha characters off the front of the string. Or, I guess a little patch to cmd.php/cactid would also be acceptable since it does not return non-numeric data.

Could you please log a ticket to http://bugs.cacti.net and then post the bug number to this post. I will publish a patch. It may take a while. I live in Detroit and it's approaching Super Bowl weekend and I will be out of town next week.

/* strip off all leading junk (the oid and stuff) */
$string = trim(ereg_replace(".*= ?", "", $string));

/* remove ALL quotes */
$string = str_replace(""", "", $string);
$string = str_replace("'", "", $string);
$string = str_replace(">", "", $string);
$string = str_replace("<", "", $string);
$string = str_replace("", "", $string);
$string = str_replace("........", "", $string);
.....

That works, but I have other ideas. Glad it's working for you. Thanks for the bug report.

Turn logging to DEBUG for one pass and you should be able to identify why the snmp and cmd scripts are not working for you. If you would like, you can post your results here. Remember to not leave DEBUG on though.

Cactid does not use /lib/snmp.php. You must edit the cactid source file(s) and then recompile. I suggest you go back to cmd.php.

[TheWitness]

This problem is associated with your snmp.conf file. Please, either delete that file or remove the entries that look similar to your error messages.

[lisa_parma]

sory, i don't know what shoul i do...
this is content of my snmp.conf:
mibdirs C:/net-snmp/share/snmp/mibs
persistentDir C:/net-snmp/snmp/persist
tempFilePattern C:/net-snmp/temp/snmpdXXXXXX

and thisi is cacti.conf massage:
#
# net-snmp (or ucd-snmp) persistent data file.
#
# DO NOT STORE CONFIGURATION ENTRIES HERE.
# Please save normal configuration tokens for cactid in SNMPCONFPATH/cactid.conf.
# Only "createUser" tokens should be placed here by cactid administrators.

Remove all entries and then save the file.
