2016-11-07check_snmp.c - Added IPv6 supportGravatar abrist
The "-6" optarg now prepends the server_address with "udp6:" for the snmpget external command as per the net-snmp syntax at: http://www.net-snmp.org/wiki/index.php/FAQ:Applications_28 Thanks to DrydenK (Roberto Greiner) for the heads up.

2014-11-28Introduce support for SNMPv3 context in check_snmpGravatar Johannes Engel
snmpget already supports using SNMPv3 contexts using the option "-n". Thus all we need to do is introduce a new argument to check_snmp and pass the argument on to snmpget using snmpget's option "-n". Since "-n" is already in use for check_snmp for a different purpose, we use "-N" instead.

2014-04-24check_snmp: Handle SNMPv3 noAuthNoPriv properlyGravatar Anton Lofgren
The SNMPv3 noAuthNoPriv security level, somewhat unintuitively, requires a security name to be passed along together with the request. Check_snmp previously did not do this, causing snmpget to throw an error: "External command error: No log handling enabled - turning on stderr logging snmpget: No securityName specified" This patch fixes the issue by always providing the security name when noAuthNoPriv is specified.

2014-01-31Handle negative values properly with check_snmpGravatar Stephane Lapie
check_snmp becomes capable of evaluating negative values properly, but it might be returning CRITICALs where it used to return OK and was ignored, if a negative value turns out to actually be a valid value. If negative values are valid, this can be worked around, by adding "~:" to the warning/critical threshold : 100 -> ~:100

2014-01-19Project rename initial commit.Gravatar Monitoring Plugins Development Team
This is an initial take at renaming the project to Monitoring Plugins. It's not expected to be fully complete, and it is expected to break things (The perl module for instance). More testing will be required before this goes mainline.

2013-08-21check_snmp: Fix support for inverse thresholdsGravatar Holger Weiss
Commit bd782990566eec91b8312cfc2765a7e2bd9e67da reintroduced support for inverse threshold ranges such as "2:1", but it broke standard thresholds such as "1:2" (by converting this range into "1") or "1:" (by converting this range into "@:2"). This commit fixes those two bugs, plus an off-by-one error while computing the number of bytes to allocate when handling inverse thresholds (two additional bytes were allocated where three were required to hold '@' and ':' and '\0'). While at it, we also check whether malloc(3) succeeded.

2013-01-29check_snmp: Close potential for using uninitialized memoryGravatar Robin Sonefors
This was reported by clang, and in order for it to understand attributes properly, I had to modify the macro that checks for non-gcc compilers. Signed-off-by: Robin Sonefors <robin.sonefors@op5.com>
2013-01-29check_snmp: Dynamically grow all data structuresGravatar Robin Sonefors
Before this patch, there was a constant, MAX_OIDS, that determined the amount of slots most (but not all - see labels) array data structures would have. It was set to 8. Some users would like to use more than that, but rather than bumping the constant, let's use the same type of logic we already use for labels - grow the space 8 slots at a time. This will allow us to potentially support an infinite amount of oids - or at least as many as the packetsize on the SNMP server allows, which is usually significantly smaller than infinity, yet often larger than 8.

2013-01-23check_snmp: Don't thrash memory when using multiple label/unit argumentGravatar Robin Sonefors
The memory allocation mixed up number of bytes with number of pointers, meaning as soon as we'd reach (on 64 bit systems) the second argument, we'd start writing it outside of our allocated memory. Normally, this isn't too visible, but as soon as you (again, on my 64 bit system) reach argument number 8, you get a segfault. It is easily reproducible with: check_snmp -o '' -l '' -o '' -l '' -o '' -l '' -o '' -l '' \ -o '' -l '' -o '' -l '' -o '' -l '' -o '' -l '' This patch allocates the proper amount of memory, to fix the issue.

2012-11-02plugins/check_snmp: Show snmp error when we fail to parse its outputGravatar Andreas Ericsson
Dying without a hint of what went wrong is just plain annoying. With this patch we at least get a hint. While at it, we fix the string offset so the output we're interested in doesn't keep the equal sign that snmpget prints. Signed-off-by: Andreas Ericsson <ae@op5.se>
2012-11-02Make check_snmp backwards compatible in how it parses thresholdsGravatar Andreas Ericsson
Once upon a time, check_snmp used to accept inverse ranges in the format of '2:1' to mean "alert if value is inside this range". Since commit 7cb3ae09334796f3b54e4e6438e38c2cc679b360, ranges such as those have instead triggered the error "Range format incorrect" and resulted in an UNKNOWN warning state. This patch attempts to fix the situation so that the old-style ranges continues to mean exactly what the once did and people with lots of snmp checks can avoid a bazillion false positives from their environments.

2010-11-30Revert "check_snmp now considers strings returned by SNMP that contain just"Gravatar Thomas Guyot-Sionnest
This reverts commit 896962a1ad1b7d7c75d42c565b06cc799feb0a7c. Conflicts: NEWS plugins/tests/check_snmp.t Notes: Reverting because I rebased a patch that was doing the same thing, plus fixing more related regressions, and both didn't work together. I kept the tests intact except for one that wouldn't pass on 1.4.14 either
2010-11-30check_snmp: Remove that is_numeric madnessGravatar Thomas Guyot-Sionnest
Original patch to make Timeticks works as in check_snmp v1.4.14, it turns out is_numeric isn't so useful and treating all types as numeric works best for backwards-compatibility. This is how it used to work in 1.4.14. As a special case, I also make calculate_rate look up for numeric values as it would otherwise return the last value instead.

2010-04-21Attempt at fixing check_snmp multiline output:Gravatar Thomas Guyot-Sionnest
This patch tries to detect and output nicely multi-line strings. This method is broken by design; only a count of double-quotes and escapes could work in every situation.
