Hi, Michael! Is there any additional perfomance, when using internal manubulon checks, rather than call it with Check Command ? Now we have some problem: we have 300 hosts and 1CPU server for icinga2. We run 3 snmp checks (disk usage, inodes, load average) and 1 http check with parsing response for each host.
This couple of check create big load average and icinga2 can't handle requests in time. As a temporary solution - we increase check interval. What is the right direction to fix this: * Send results via API * Use internal checks, they would be faster. why ? * don't check 300 hosts http request, use http-pool * just upgrade your server to more CPU. Is there any example - how many checks and how many CPU have the server. 12.04.2016, 15:51, "Michael Friedrich" <michael.friedr...@netways.de>: > Hi, > > btw - if you are using the manubulon-snmp check plugins, there are additional > CheckCommand definitions available directly from Icinga 2. > > http://docs.icinga.org/icinga2/latest/doc/module/icinga2/toc#!/icinga2/latest/doc/module/icinga2/chapter/plugin-check-commands#snmp-manubulon-plugin-check-commands > > So you do not necessarily need to create your own CheckCommand definitions :) > > Kind regards, > Michael > >> On 12 Apr 2016, at 14:49, Romaneev Vasily <enter...@yandex.ru> wrote: >> >> I choose snmp-based checks for agentless checks. >> >> Some examples from my config: >> Create check commands - set some default variables >> >> object CheckCommand "check_snmp_storage" { >> import "plugin-check-command" >> >> command = [ PluginDir + "/check_snmp_storage" ] >> arguments = { >> "-H" = "$address$", >> "-l" = "$snmpv3user$", >> "-x" = "$snmpv3pass$", >> "-m" = "$snmp_disk$", >> "-q" = "$diskType$", >> "-r" = { >> set_if = "$disk_not_regexp$" >> description = "Do not use regexp on Disk mountpoint" >> } >> "-w" = "$snmp_disk_w$" >> "-c" = "$snmp_disk_c$" >> "-f" = "$snmp_disk_perf_data$" >> "-R" = "$reserved_root_space$" >> } >> vars.snmpv3user = "snmpv3login" >> vars.snmpv3pass = "snmpv3password" >> vars.snmp_disk = "/" >> vars.diskType = "FixedDisk" >> vars.disk_not_regexp = false >> vars.snmp_disk_perf_data = true >> vars.reserved_root_space = 5 >> vars.snmp_disk_w = "90%" >> vars.snmp_disk_c = "95%" >> } >> >> Next i apply Service to a hosts: >> apply Service "check_snmp_storage" { >> import "generic-service" >> check_command = "check_snmp_storage" >> check_interval = 1800 /* 10 min*/ >> retry_interval = 1800 >> max_check_attempts = 2 >> #ignore where host.name >> assign where host.name >> assign where host.name == "next-test.com" >> vars.notification["slack_major_storage"] = { devops_channel = [ >> "icingaadmins" ] } /*some notification handlers*/ >> vars.notification["slack_service_storage"] = { devops_channel = [ >> "icingaadmins" ] } /*some notification handlers*/ >> } >> >> 12.04.2016, 13:48, "Meti, Shantala (NFV BU)" <shantala.m...@hpe.com>: >>> Thanks. >>> >>> How default services like disk, ssh etc works in agentless icinga2. >>> >>> I have two VMs where in one VM icinga2 is running and another VM is a >>> spare VM.
