Module: check_mk Branch: master Commit: cdf4163585d35c0aff6522670e8905336c255351 URL: http://git.mathias-kettner.de/git/?p=check_mk.git;a=commit;h=cdf4163585d35c… Author: Sebastian Herbord <sh(a)mathias-kettner.de> Date: Tue Mar 8 14:32:57 2016 +0100 3094 FIX cisco_temperature: fixed duplicated sensors on some devices On some cisco devices, temperature sensors were discovered twice under different names. This has now been fixed and best effort has been made to properly merge available information of the two. --- .werks/3094 | 12 ++++++++++ ChangeLog | 1 + checks/cisco_temperature | 56 ++++++++++++++++++++++++++++++++++------------ 3 files changed, 55 insertions(+), 14 deletions(-) diff --git a/.werks/3094 b/.werks/3094 new file mode 100644 index 0000000..7ac0c92 --- /dev/null +++ b/.werks/3094 @@ -0,0 +1,12 @@ +Title: cisco_temperature: fixed duplicated sensors on some devices +Level: 1 +Component: checks +Class: fix +Compatible: compat +State: unknown +Version: 1.2.9i1 +Date: 1457443808 + +On some cisco devices, temperature sensors were discovered twice under different names. +This has now been fixed and best effort has been made to properly merge available information of the +two. diff --git a/ChangeLog b/ChangeLog index eb82124..89424d0 100644 --- a/ChangeLog +++ b/ChangeLog @@ -69,6 +69,7 @@ * 3278 FIX: fritz_wan_if: Fixed incorrect unit Bit used in check * 3092 FIX: isc_dhcpd: fixed incorrect handling of timezones * 3259 FIX: ad_replication: fixed wrong timestamp handling + * 3094 FIX: cisco_temperature: fixed duplicated sensors on some devices...
