Nagios Support Forum

Hi,

I have compiled Nagios 3.4.1 for Solaris, everything seems to be working fine, but the check_swap pluging

The plugin itself was missing from /usr/local/nagios/libexec, so I checked the nagios-plugins-1.4.15 source and compiled it individually

root@ukbhu023p:~/nagios-plugins-1.4.15/plugins# make check_swap
gcc -DLOCALEDIR=\"/usr/local/nagios/share/locale\" -DHAVE_CONFIG_H -I. -I.. -I.. -I../lib -I../gl -I../intl -I/usr/include -DNP_VERSION='"1.4.15"' -g -O2 -MT check_swap.o -MD -MP -MF .deps/check_swap.Tpo -c -o check_swap.o check_swap.c
mv -f .deps/check_swap.Tpo .deps/check_swap.Po
/bin/sh ../libtool --tag=CC --mode=link gcc -DNP_VERSION='"1.4.15"' -g -O2 -L. -o check_swap check_swap.o -lm utils.o ../lib/libnagiosplug.a ../gl/libgnu.a popen.o -lpthread -ldl
libtool: link: gcc "-DNP_VERSION=\"1.4.15\"" -g -O2 -o check_swap check_swap.o utils.o popen.o -L/root/nagios-plugins-1.4.15/plugins -lm ../lib/libnagiosplug.a ../gl/libgnu.a -lpthread -ldl

I then copied the check_swap to /usr/local/nagios/libexec

Now it always returns the following

SWAP CRITICAL - 100% free (0 MB out of 0 MB)

Any ideas?

Thanks in advanced!

PD: I do have swap.. 1Gb

root@ukbhu023p:/usr/local/nagios/libexec# swap -l
swapfile dev swaplo blocks free
/dev/zvol/dsk/rpool/swap 228,2 16 2097136 2097136

Hmm, I will try to get in contact with our Solaris guy, in the meantime have you taken a look at this:

hi Slansing,

Thanks for your post, that .pl works just fine, it provides info on Virtual memory not disk-swap, but good enough for me. It would be good to have the native tools working though.. also in terms of CPU consumption..

I am facing a different issue now..

/usr/local/nagios/libexec# ./check_procs
System call sent warnings to stderr: pst3: This program can only be run by the root user!root@ukbhu023p:/usr/local/nagios/libexec
/usr/local/nagios/libexec# ./check_procs -vv
CMD: /usr/local/nagios/libexec/pst3
System call sent warnings to stderr: pst3: This program can only be run by the root user!root@ukbhu023p:/usr/local/nagios/libexec
/usr/local/nagios/libexec# file /usr/local/nagios/libexec/pst3
/usr/local/nagios/libexec/pst3: ELF 64-bit MSB executable SPARCV9 Version 1, dynamically linked, not stripped

The only information I have found researching state that it might have been compiled for 32bits, but I checked the config.log and it was compiled for 64 bits..

Thanks in advanced.

Regards

Hi,

I have solve the pst3 issue, apparently it does not check the running credentials but the owner of the binary itself!

root@ukbhu023p:/usr/local/nagios/libexec# chown root:root pst3
root@ukbhu023p:/usr/local/nagios/libexec# ./pst3 | head

Ahhh! Sounds good, I will pass this information on to the Solaris Dev when he is in.

akame,

You are correct that the binary version of check_swap was not included with the agent. If I recall correctly, the reason is that it needs to run setuid root (or nrpe needs to run as root) in order for it to work. That presents security issues, so I included a perl version, which you have already discovered.

There is also a custom_check_procs script that should provide the same functionality as the check_procs binary.

Hope that helps,

Eric
