HOST_NETWORK_INTERFACES_SLOW_MODE

[#1]

hello cloudera comunity ,

we are having the next issue from   cloudera manager

The health test result for HOST_NETWORK_INTERFACES_SLOW_MODE has become unknown: Not enough data to test: Test of whether the host has network interfaces that appear to be operating at less than full speed.

also we make a research for this and the interface speed looks fine and there is no restrictions of velocity.

any one have a issue like this ?

the version of  cloudera its Versión: Cloudera Enterprise 5.14.4

@rhad84 The "unknown" statuses are normally when the agent could not collect monitoring data or the data had “unkonwn” status.

Specifically when Agent attempted to collect network interface speed, the device didn't return any data or the data returned was “Unkonwn” at the time period of the alert.

The collection is equivalen to the doing ethtool <device name>

# Expected behaviour
[root@nightly70x-1 ~]# ethtool eth0
Settings for eth0:
Supported ports: [ ]
Supported link modes: Not reported
Supported pause frame use: No
Supports auto-negotiation: No
Supported FEC modes: Not reported
Advertised link modes: Not reported
Advertised pause frame use: No
Advertised auto-negotiation: No
Advertised FEC modes: Not reported
Speed: 10000Mb/s <<<<<<<<<<<<<<<<<<<<<<<<<<<<< THIS
Duplex: Full <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< THIS
Port: Twisted Pair
PHYAD: 0
Transceiver: internal
Auto-negotiation: off
MDI-X: Unknown
Link detected: yes

Example of "Unknown" is : 

So you have to fix this at network level or you can suppress the Alerts if you think networking is good.
