EMC Unity-500 - stopped collecting CPU perf counter values

Hello:

I have a DELL EMC Unity-500 array from which I can no longer collect CPU values for SPA (SPB values are collected just fine).

When I test the connectivity using UEMCLI, I'm noticing that the self signed SSL certificate just expired:

/usr/bin/uemcli -d <storage_IP> -u stor2rrd -p '<passwd_here>' -noHeader /sys/general show -detail
Remote certificate:
Issuer:     CN=<storage_Name>
Subject:    CN=<storage_Name>
Valid from: 2016-08-17 18:31:26 Z
Valid to:   2019-08-17 18:31:26 Z
Serial:     <whatever_serial>
Id:         <whatever_ID>
Would you like to:
  [1] Accept the certificate for this session
  [2] Reject the certificate
Please input your selection (The default selection is [1]):
1:    System name             = <storage_Name>
      Model                   = Unity 500
      Platform type           = EMC Storage System
      UUID base               = 0
      Product serial number   = <whatever_serial>
      Auto failback           = on
      Health state            = OK (5)
      Health details          = "The system is operating normally."
      Power (Present)         = 2252 watts
      Power (Rolling Average) = 2252 watts
      Supported SP upgrades   = SP600

If the expired certificate is the reason, then why I'm still able to collect all the other counters?

Please advise on a possible solution.

Sincerely,

Alex H.
