Your cert was issued from a internal CA and it is not trusted, so you need to import the root for your internal CA into the cert store used by arcgis monitor. Many of the more common root CA are already preinstalled in the cacerts file. You can use keytool.exe in the folder C:\ArcGIS Monitor\framework\runtime\jre\bin to see what root certs are pre installed and explore some other things. Lots of documentation on this tool.
Step 1
Export the root cert for your internal CA from your browser to C:\temp\PKICorpRootCA.cer. the export file format should be Base 64 encoded x.509
These are the ROOT CA I have as shown in Chrome browser

You could also just export the root CA to file from the certification Path *******SDCP01-CA you show in you initial posting. Whatever works for you.
Example to import the root cert from the file C:\temp\PKICorpRootCA.cer from your internal CA:
cd C:\ArcGIS Monitor\framework\runtime\jre\bin
keytool -import -trustcacerts -keystore "C:\ArcGIS Monitor\framework\runtime\jre\lib\security\cacerts" -storepass changeit -alias pki_root -file C:\temp\PKICorpRootCA.cer
Thats my guess!
