Two Health Monitor One Failing Pool is down.

Why would the entire pool be down if only one health monitor is failing?

 

How can i change it so the pool is not down when only one health check is failing but would go down if both are failing.

 

2 node

 

MON-CC01 MON-CC02

 

2 ports

 

8665 8666

 

2 nodes:

 

  • Green MON-CC0X
  • Red MON-CC0X

Each node has a custom health monitor:

 

  • MON-CC01-866X

     

    • NameMON-CC01-866X
    • Partition / PathCommon
    • Description
    • TypeTCP
    • Parent Monitortcp
    • Interval 5 seconds
    • Timeout16 seconds
    • Send String
    • Receive String
    • Receive Disable String
    • Reverse Yes X No
    • Transparent Yes X No
    • Alias Address 10.51.76.42
    • Alias Service Port 866X
    • Adaptive Enabled

2 Pool

 

  • Red MON-CC-866X-Pool
  • Red MON-CC-866X-Pool

Both Pools are red

 

Looking at the members of each pool i see the following:

 

  • Node NameMON-CC0X
  • Address10.51.76.41
  • Service Port8665
  • Partition / PathCommon
  • Description

  • Go into your pool and under the health monitors said the "Availability Requirement" to "At least" and then the number of monitors you want to be running before it fails. So if you have two monitors, set this to one. So as long as one monitor is still actively working, it doesn't kill that member.
