[Uptime] Transition link to Logs, Infra UI contains host.ip:null if monitor.status:down

[v01t]

Kibana version: 7.4.0

Elasticsearch version: 7.4.0

Server OS version: Centos 7

Browser version: Firefox 69.0.3

Browser OS version: Debian 10.1

Original install method (e.g. download page, yum, from source, etc.): Docker

Describe the bug:
Transition links from Uptime UI to Logs/Infra UI's contains host.ip:null instead of host.ip:<ip_value> and looks like:

/app/infra#/infrastructure/inventory?waffleFilter=(expression:'host.ip : null',kind:kuery)
/app/infra#/logs?logFilter=(expression:'host.ip : null',kind:kuery)

when last monitor.status: down

Steps to reproduce:

1. Find monitor with current status:down (monitor should be shown as "Down", also specific time frame can be used to get the same from recovered monitors)
2. check the links for "Show host metrics", "Show host logs" (probably others too)

Expected behavior:
Transition links suppose to contain value of host.ip in the url as its happen when monitor.status:up

i tried reproducing it, but i am unable to in 7.4 as well in master. For me it always contains ip even if monitor is down.

[v01t]

additionally I verified monitor records to ensure that host.ip are present in source object, field type in heartbeat and filebeat/metricbeat indices for host.ip = ip.

here is screenshot (see hover-link destination on the bottom)

Please let me know if you will need any other additional information that may help resolve the issue I would be happy to provide it.

@v01t when you expand the rows on the page do you see any IPs listed? That would be a key clue here.

[v01t]

@andrewvc no I do not see IP listed in expanded row for check with current status "down":

if I select time frame with end-timestamp that equals to last registered "down" status for the check 1 from the screenshot (to have both of them with status "down") IP disappears for both of them.

Thanks for your reply and help.

I believe this is fixed in #50138 .

Closing this issue, if it persists post 7.6.0 please let us know.

Thanks for the detailed writeup!

Just to close the loop here, the issue seems to be that there was some issue where no IP was present. This can happen if the DNS lookup fails for instance.
