The connection to MongoDB Altas had spiked up to max suddenly and decreased to the normal rate among two days

I have found out the connection to our MongoDB server has suddenly spiked up.

so I downloaded connection log and found IP: and Application MongoDB Automation Agent occupied the most of logs

Why MongoDB Automation Agent suddenly connects to our server so much ?

,{“t”:{"$date":“2022-09-19T13:42:53.152+00:00”},“s”:“I”, “c”:“NETWORK”, “id”:51800, “ctx”:“conn280777”,“msg”:“client metadata”,“attr”:{“remote”:“”,“client”:“conn280777”,“doc”:{“driver”:{“name”:“mongo-go-driver”,“version”:“v1.7.2+prerelease”},“os”:{“type”:“linux”,“architecture”:“arm64”},“platform”:“go1.17.6b7”,“application”:{“name”:“MongoDB Automation Agent v12.3.4.7674 (git: 4c7df3ac1d15ef3269d44aa38b17376ca00147eb)”}}}}

the log above occupies most of proportion among connection logs
I have checked out that this IP on 17th September was around 10,000 connection but on 18th and 19th, spiked up to 30,000 connections

On 20th September ,the connection decreased down to the normal rate and it seems increasing gradually now.

That’s what I found and I am trying to find out another reason…but I don’t know yet.

What can be the reason for the sudden spiking connection rate??
