Google can not find much information, see a saying: is some platform Interface manager. Do not dare to kill, and then check the data.
Look at the professional saying:KIPMI is supposed to run with the low priority. When you say it consumes 70-90% of the CPUs, was that constant (does it still consume the processor when they are other TAS KS in the process queue this should have a larger slice of the CPU time) or the 70%/90% comes when the machine is idle?A second issue to investigate are whether

Nagios:
Advantages:
1, can monitor a lot of agreements: (Http,ftp,ssh,smtp,pop3,smtp,mysql)
Mail or SMS notification, the proxy client can run in many places
2, fault jitter detection
3, a lot of plug-ins to use

1, file-based configuration, inconvenient expansion, poor readability, management time, how many services may need to monitor how many files.

monitoring system, in the use of large-scale environment, has surpassed the Zabbix, to solve the pain point of this user. However, the monitoring function of this system may not be as strong as Zabbix (after all, the ability to provide agent, SNMP, IPMI, JMX, WEB, SSH, TELNET, extended monitoring scripts, and customizable open source monitoring system is really not a lot)。 AlthoughZabbix 3.2 also introduces the technology of tag, but to achieve this
