2013-08-18NEWS: Mention the new "check_snmp --offset" optionHolger Weiss1-2/+2
... and apply two small cosmetic changes to check_snmp.c. Closes #59.
2013-08-18added --offset option to allow adjustment of sensor dataSimon Kainz1-1/+9
2013-08-18check_snmp: Allocate space for the new -Le optionHolger Weiss1-2/+2
Closes #41.

2013-01-23check_snmp: Don't thrash memory when using multiple label/unit argumentRobin Sonefors1-11/+11
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.

2012-11-03plugins/check_snmp: Show snmp error when we fail to parse its outputAndreas Ericsson1-2/+2
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>
2012-11-03Make check_snmp backwards compatible in how it parses thresholdsAndreas Ericsson1-0/+23
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.

2012-06-29Die when asprintf failsAnders Kaseorg1-17/+17

2012-06-26check_snmp: use single quotes for perf data labelsSven Nierlein1-3/+3
2012-06-26Fix performance data label containing spaces in check_snmp (Jochen Bern)Sven Nierlein1-3/+23
Add --perf-oids option for check_snmp to retain optional 1.4.14 compatibility
2012-02-24Cosmetic changeHolger Weiss1-7/+7
Replace all occurrences of "strstr(s, "c") == s" with "s[0] == 'c'".
2012-02-24Accept multiple labels specified with "-l"Holger Weiss1-3/+3
Fix the code which accepts a comma-separated list of labels specified via the "-l" option. (Spotted by Oskar Liljeblad in Debian bug report #647020, forwarded by Jan Wagner.)
2010-12-01Revert "check_snmp now considers strings returned by SNMP that contain just"Thomas Guyot-Sionnest1-14/+0
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
2010-12-01check_snmp: Remove that is_numeric madnessThomas Guyot-Sionnest1-8/+4
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.

2010-04-22Replace the lousy multiline parser with a robust one.Thomas Guyot-Sionnest1-8/+49
This one counts double quotes and backslashes so it should handle any level of escaping.
2010-04-22Attempt at fixing check_snmp multiline output:Thomas Guyot-Sionnest1-3/+17
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.
2010-04-14Fix translations when extra-opts aren't enabledThomas Guyot-Sionnest1-8/+8
Bug #2832884 reported problem with translations outputting pot file headers. This is caused by "" matching the header of the translation files. This patch moves gettext macros inside utils macros and update some french translations.
2010-03-31check_snmp: Update last patch to copy value verbatimThomas Guyot-Sionnest1-10/+6
Rework last patch, copying the converted portion of the string rather than re-converting it. This is safer for backwards-compatibility as the value is never modified.
2010-03-31check_snmp: Fix regression introduced in #1867716Thomas Guyot-Sionnest1-2/+10
Bug #1867716 fixed what it meant to fix: broken perfdata strings. Unfortunately some users relied on half-broken perfdata string where at least the first token was OK. This patch do a two-way conversion (string to double then back to string) instead and use the conversion result for the performance data. A possible caveat is that the string may change where it normally shouldn't but the result should be somewhat similar.

2009-05-28check_snmp: Make use of standard threshold functionsThomas Guyot-Sionnest1-197/+53
This patch makes use of standard threshold functions. This allows using doubles as thresholds. Since SNMP supports only integers, double precision numbers are only printed when parsed from a STRING type. In addition, support for printing properly Timeticks type has been added, and the code has been thoroughly cleaned.
