SNMP2 & commvault error, MIB + convert to Zabbix Template

[GreenHorn]

Hello folks,
I am a new in Zabbix/monitoring . I need monitor the commvault system on Microsoft 2019. I can't find some MIB file with OID for commvault. So I am trying find OID via snmpwalk -v2c -c public *domain.name* .1. I am using DN for differeding of Commvault and OS. But when is command runnig
1) I get this error:

SNMPv2-SMI::enterprises.77.1.1.1.0 = STRING: "10"
SNMPv2-SMI::enterprises.77.1.1.2.0 = STRING: "0"
SNMPv2-SMI::enterprises.77.1.1.3.0 = Hex-STRING: 07 00 00 00
Error in packet.
Reason: (genError) A general failure occured
Failed object: SNMPv2-SMI::enterprises.77.1.1.3.0

Is there someone with experience with this?

2) I need monitor from backup system (commvault) these parts via snmp:

• File system capacity(backed up & stored)
• File system efficienty( compression factor)
• CPU usage
• NVRAM usage
• ENvironmental (for example: power, temperature, fan)
• replication lag time status
• retention period
• backup software
• the archive software success status od archive jobs from the master server
• The status of the infrastucture servers which make up the nevironment

3)Do you know , how convert MIB as Template for zabbix?

Thank you for any idea or steps.
