How to analyze the object and threshold part of nrpe monitoring

How to analyze the nrpe monitoring object and threshold part, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

Nrpe monitoring objects and thresholds:

Monitoring object

Monitoring threshold

Machine

Capital

Host survival:

Check_ping

-w 3000.0c80%-c 5000.0100%-p 5 (within 3000 millisecond response time

A warning is given when the packet loss rate exceeds 5000. Within the response time of 80 milliseconds, the packet loss rate exceeds

100% critical, a total of 5 packets were sent)

Login user:

Check_user

-w 5-c 10 (w for warning, c for critical)

System load:

Check_load

-w 15pyrrine 10pr 5-c 30pr 25pr 20 (1 minute, 5 mins, 15 mins is greater than the corresponding one

The number of waiting processes is warning or critical)

Disk occupancy:

Check_disk

-w 20%-c 10%-p / (20% warning of the total size of the remaining space in the root partition

10% critical,-p followed by root partition)

The script detects the disk Imax O:

Check_iostat

-w 5-c 10 (more than 5% of disk iowait reports warning, more than 10% reports emergency)

Detect zombie processes:

Check_zombie _ procs

-w 5-c 10-s Z (5 zombie process warnings, 10 critical)

Total number of processes detected:

Check_total_procs

-w 150-c 200 (total process to 150 warnings, 200 critical)

The script detects the remaining memory:

Check_mem

-w 90%-c 95% (memory idle rate more than 90% warning, more than 95% critical)

Detect swap partition usage:

Check_swap

-w 20%-c 10% (20% warning of the total size of the remaining space in the swap partition

10% critical)

Monitoring service port:

Check_tcp

-H localhost2-p 80 (host and corresponding port number)

Monitor page response time:

Check_http

-H localhost2-u http:\ /\ / localhost2/test.jsp-w 5-c 10 (check page, report warning for more than 5s, report emergency for more than 10s)

Number of IP connections detected by script:

Check_ips

-w 200-c 250 (IP connections over 200 warnings, over 250 critical)

Flow

Monitor and control

Monitor server traffic:

Check_traffic

-V 2c-C public-H localhost2-I 2-w 12Magi 30-c 15jade 35-M-b (snmp version, user, mainframe, corresponding Nic, warning threshold, critical threshold)
