1 Frequently Asked Questions
2 **************************
4 Q: Where can I find documentation for <insert name> plugin?
6 A: All plugins that comply with minimal development guideline for
7 this project include internal documentation. The documentation
8 can be read executing plugin with the -h or --help option. If
9 the '-h' option does not work, that is a bug.
12 Q: What version of <insert name> plugin am I running?
14 A: All plugins that comply with minimal development guideline for
15 this project include detailed version information. When executed
16 with the '-V' option, a version string will be printed:
18 check_radius (nagios-plugins 1.3.0-alpha1) 1.11
20 Note that this string include both the assigned package release
21 name and the CVS-generated revision for the individual plugin.
22 Authors should strictly adhere to this format. All bug reports
23 and help requests should reference this information.
26 Q: What information do I need to include when asking for help or
27 submitting a bug report?
29 A: At a minimum, the output from 'uname -a' and the version string
30 from '<plugin_name> -V' and, of course, a description of the
31 problem and any solution/patch.
34 Q: I'm using Redhat Linux (or some other RPM-based distribution).
35 Which packages should I install?
37 A: The package nagios-plugins-<version>.<arch>.rpm contains only
38 those plugins that should work on any POSIX compliant system. In
39 other words, you should be able to install this package on your
40 system, no matter what else is or in not installed.
42 However, most of us have more complex systems than barebones
43 POSIX. We tried creating a variety of separate packages so
44 each dependency could be installed cleanly, but many people
45 found that this resulted in too many packages. So in the end,
46 all the non-POSIX plugins were folded into one RPM
47 (nagios-plugins-<version>.<arch>.rpm). Most people will need to
48 use RPM's '--nodeps' option to install this package.
51 Q: My system uses the .deb package format. What packages should I
52 install?
54 A: We strive for cooperation between all packagers and developers.
55 The answers for .deb are the same as for RPM, after changing the
56 package name suffixes accordingly.
59 Q: I prefer to build my own RPMs. Do I need to install all of the
60 various dependencies?
62 A: Beginning with the 1.2.9-1 release, you may run
64 rpm --define 'custom 1' -ta nagios-plugins-<release>.tar.gz
66 In prior releases, you must unpack the tarball and build the
67 RPM using nagios-custom.spec with 'rpm -ba'.
70 Q: I get an error like
72 Warning: Return code of 127 for check of service 'PING' on host 'anyhost' was out of bounds.
74 when I run Nagios. (Often check_ping runs just fine on the
75 command line).
77 A: Commonly, system administrators will make security as tight as
78 possible on the monitoring system. Sometimes this includes OS
79 options or hardening scripts that prevent unprivileged users from
80 running the ping command. Nagios runs with no more privileges
81 than 'nobody' -- check to be sure that the nagios user can
82 actually run check ping. (This can also happen with other binaries
83 executed by nagios, but ping seems to be far and away the biggest
84 offender.)
87 Q: I have a plugin to offer. What can I do?
89 A: You can make it available on NagiosExchange (http://nagiosexchange.org)
90 where other people can find it for use.
92 You can also get feedback on improving the plugin via the
93 nagiosplug-devel@lists.sourceforge.net mailing list.
