2.0.0-beta.2

Added

• Added full implementation of the CLEARFLAP API command (#113)

• Log warning if secrets file is world-readable (#280)

• Only load and parse pollfile if it has been changed since last load (#282)

• Added customized logging of multiple traps, just as in Zino 1:

  • CISCOTRAP-MIB::reload
  • CISCO-CONFIG-MAN-MIB::ciscoConfigManEvent
  • CISCO-PIM-MIB::ciscoPimInvalidRegister
  • CISCO-PIM-MIB::ciscoPimInvalidJoinPrune
  • OSPF-TRAP-MIB::ospfIfConfigError

  (#319)

• Added support for tracking accumulated event downtime for reachability and portstate events (#332)

• Custom logging configuration can now be applied in zino.toml

Changed

• Rename/alias BGP and Juniper alarm event attributes in order to have more useful variable names in Python code, while retaining aliases that are compatible with the legacy API protocol (#352)

Fixed

• Properly use dashes in event attribute names in the legacy API (#281)
• Use Zino 1-compatible field names for serialization of planned maintenance (#287)
• Use Zino 1 field names for serialization of BGP/BFD events (#331)
• Match against port alias instead of port description when match_type is regexp or str for portstate maintenance events. Still matches port description for intf-regexp. (#297)
• Fix BGP-related Pydantic serialization warnings (#312)
• Stop logging empty interface descriptions on first discovery (#314)
• Reschedule devices whose configuration attributes where changed in the pollfile (#330)
• Use default interval from pollfile to stagger new jobs (#337)
• When matching an event to a planned maintenance, check that event is of the correct subclass (#344)
• Avoid potential state corruption issues by saving the running state to a temporary file before overwriting the existing state file (#364)
• Properly encode timedelta values as an integer number of seconds in the legacy API

Changed

• Handle errors from changed SNMP interface in Juniper alarm task (#212)

• Legacy API now correctly hides closed events (#192)
• Legacy API now correctly denies re-opening of closed events (#201)
• BFD events now have the expected lastevent attribute (#200)
• Fixed potential bug with how portstate events are indexed internally in Zino's running state (#206)

2.0.0-alpha.1

This is the first official release of Zino 2. This is an alpha release. It mostly works, but still has several features missing compared to the original Zino.
