Can't locate RRDs.pm

I'm sure you'll all sick of see people asking about this error, but I
can't seem to find an answer so I guess I'll need to ask :)

When running ./collector I get and error that looks something like this
"Can't locate RRDs.pm in  <at> INC ( <at> INC contains: /home/cricket/cricket/lib
............"

I installed RRD exactly as the instructions in
"rrdtool-1.2.15/doc/rrdbuild.txt" explained - I did not have any problem
at all and RRD compiled like a charm.

I also then remember to run make site-perl-install as "Installing
Cricket for the Complete Beginner" indicated.

In the RRD/bindings folder I see that I now have what I guess is the
compiled RRD perl module, but I guess I must have done something wrong
as they are clearly not located somewhere that Cricket can find them.

Where did I wrong here and what can I do to correct the problem?

Thanks
Warrick

Does cricket have permission to enter the directory and read files from it?

Ah thanks Stephen, I ran chown -R cricket.cricket * in the binding
folder and that seems to have done it ... great stuff.

I tried running collector again and now get the following:

Can't load
'/usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi/auto/RRDs/RRDs.so'
for module RRDs: librrd.so.2: cannot open shared object file: No such
file or directory at
/usr/lib/perl5/5.8.5/i386-linux-thread-multi/DynaLoader.pm line 230.
 at ./collector line 32
Compilation failed in require at ./collector line 32.
BEGIN failed--compilation aborted at ./collector line 32.

I'm guessing this has something to do with your "and read files from it"
part of the statement.

Line 32: is

use lib "$Common::global::gInstallRoot/lib";
use RRDs 1.000101;

Which is defined in "cricket-conf.pl" as:

package Common::global;

Thanks Steven,

I like the way you're thinking and I'm so close I can feel it ...

ldd is unfortunately not listing the expected location though .

# ldd
/usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi/auto/RRDs/RRDs.so
        librrd.so.2 => not found
        libm.so.6 => /lib/tls/libm.so.6 (0x00b23000)
        libc.so.6 => /lib/tls/libc.so.6 (0x00de9000)
        /lib/ld-linux.so.2 (0x007b1000)

looking back at my install notes, I see that I set the Env variable as
INSTALL_DIR=/usr/local/rrdtool-1.2.15

and running locate shows that this is indeed where it is located.

You're a legend! - Thanks mate, that worked like a charm.

Quick and dirty solution is to put a symlink in a 'standard' lib directory.

# ln -sf /usr/local/rrdtool-1.2.15/lib/librrd.so.2.0.8  \
/usr/lib/librrd.so.2

I do this, it works.

A purist would probably set LD_LIBRARY_PATH in his crontab and in httpd.conf

It can't find librrd.so.2.

My setup does but your's appear to be looking in

/usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi/auto/RRDs/

try

# ldd \
/usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi/auto/RRDs/RRDs.so

to find out where perl expect to find out where RRDs.so expects to find 
the missing library.

Automatically drawing every element of an SNMP MIB tree?

Hello

Is it possible to draw one one graph for every sensor that is below a
specific OID tree without having to configure the exact leaf OIDs?

Foundry Routers have several slots with interface cards, with varying
numbers of temperature sensors. Their snmpwalk output look like:

	$ snmpwalk router01-xyz FOUNDRY-SN-AGENT-MIB::snAgentTempValue
	FOUNDRY-SN-AGENT-MIB::snAgentTempValue.1.1 = INTEGER: 76  \ two
	FOUNDRY-SN-AGENT-MIB::snAgentTempValue.1.2 = INTEGER: 123 /
	FOUNDRY-SN-AGENT-MIB::snAgentTempValue.2.1 = INTEGER: 92  \ two
	FOUNDRY-SN-AGENT-MIB::snAgentTempValue.2.2 = INTEGER: 125 / 
	FOUNDRY-SN-AGENT-MIB::snAgentTempValue.5.1 = INTEGER: 71  \ two
	FOUNDRY-SN-AGENT-MIB::snAgentTempValue.5.2 = INTEGER: 95  /
	FOUNDRY-SN-AGENT-MIB::snAgentTempValue.6.1 = INTEGER: 75  \ two
	FOUNDRY-SN-AGENT-MIB::snAgentTempValue.6.2 = INTEGER: 103 /
	FOUNDRY-SN-AGENT-MIB::snAgentTempValue.7.1 = INTEGER: 68  <- one
	FOUNDRY-SN-AGENT-MIB::snAgentTempValue.8.1 = INTEGER: 68  <- one

The graph description may be auto generated as well, like "sensor 6.1", 
that would be ok.

thanks,

-christian-

Re: Automatically drawing every element of an SNMP MIB tree?

Hi,

yes, you can generate cricket config files by postprocessing eg. snmpwalk 
output with a shell or perl script.  There is no function in cricket that 
does this automatically.

 Michael
