Probably the memory monitoring is not correct:

CRITICAL: Memory total: 318.19 MB used: -265.34 MB (-83.39%) free: 583.53 MB (183.39%) | 'memory.usage.bytes'=-278234112B;;;0;333642752 'memory.free.bytes'=611876864B;;;0;333642752 'memory.usage.percentage'=-83.39%;0:80;0:90;0;100
.1.3.6.1.4.1.248.11.22.1.8.1.0 = 1
.1.3.6.1.4.1.248.11.22.1.8.11.1.0 = 325823
.1.3.6.1.4.1.248.11.22.1.8.11.2.0 = 597536
.1.3.6.1.4.1.248.14.2.15.1.0 = undef
.1.3.6.1.4.1.248.14.2.15.3.1.0 = undef
.1.3.6.1.4.1.248.14.2.15.3.2.0 = undef

As I understand from this data:

• used memory: .1.3.6.1.4.1.248.11.22.1.8.11.1.0 = 325823
• free memory: ..1.3.6.1.4.1.248.11.22.1.8.11.2.0 = 597536

But the SNMP MIB seems different looking this documentation: https://mibs.observium.org/mib/HM2-DIAGNOSTIC-MIB/

• ram allocated: .1.3.6.1.4.1.248.11.22.1.8.11.1.0 = 325823
• ram free: ..1.3.6.1.4.1.248.11.22.1.8.11.2.0 = 597536
• ram used: free + allocated?

If i understand the allocated is the ram used (not the total). It's not very clear in the mib file. I can fix it.
