[1397706401] Error: Could not load module '/usr/local/icinga/lib/idomod.so' -> /tmp/icinganebmodWoV8IA: failed to map segment from shared object: Operation not permitted [1397706401] Error: Failed to load module '/usr/local/icinga/lib/idomod.so'.
A
因為我的 /tmp 有設定 noexec 所以我就把 tmp 放到別的地方去，編譯時就加上如下 --with-temp-dir=/usr/local/icinga/var --with-temp-file=/usr/local/icinga/var/icinga.tmp
Q
如果在 icinga-core 裡 ./configure 加上 --enable-embedded-perl --with-perlcache 後，再 make 時 ../include/epn_icinga.h:30:20: error: EXTERN.h: No such file or directory
A
目前還沒研究解法
Q
在 icinga 介面上遇到 "Warning: Status data OUTDATED! Last status data update"

調整 my.cnf 效能使用 比方說參考 /usr/share/mysql 裡的 my-huge.cnf
Q
[1398763667] Warning: Breaking out of check result reaper: max reaper time (30) exceeded. Reaped 32 results, but more checkresults to process. Perhaps check core performance tuning tips?
A
因為使用 nsca + command 後，大量 checks 讓效能差，所以可以用 nsca + ocp daemon 改善
Q
icinga classic UI 介面上看到的三個數值，Unacknowledged / acknowledged / Handled 有什麼不同
A
https://www.mail-archive.com/icinga-users@lists.sourceforge.net/msg01576.html Unacknowledged == THE SKY IS FALLING! Acknowledged == It broke, but it's being attended to Handled == We planned on breaking this host/service on purpose; nothing to see here, move along. (in addition for services, the host was Acknowledged) --> "Unacknowledged" means a check you were expecting to return UP/OK returned for that particular state (Down, Critical, Warning etc) and it hasn't been acknowledged... in other words these are "real" problems that haven't gotten any attention yet, at least as far as Icinga knows. --> "Acknowledged" means a check you were expecting to return UP/OK returned for that particular state (Down, Critical, Warning etc), but that someone has acknowledged it. Which means someone has told Icinga that they know about it and it can (hopefully) be assumed that it is being dealt with in some fashion. --> "Handled" means a check you were expecting to probably *NOT* return UP/OK returned for that particular state (Down, Critical, Warning etc). Handled is determined when a host or service is in scheduled downtime or in the case of services, also when its host has been acknowledged. In a way, scheduled downtimes are kind of like a pre-acknowledgement of a purposely made issue/outage which makes them a distinctly different type of event than something that is a surprise and needs to be Acknowledged after the fact.
