Osis Model Specs

• A model.category is placed under the osis application inside the namespace the model represent.
• Example.

  [rootmodel:alert] @index
    prop:id int,,
    prop:gid int,,
    prop:nid int,,
    prop:description str,,
    prop:descriptionpub str,,
    prop:level int,, 1:critical, 2:warning, 3:info
    prop:category str,, dot notation e.g. machine.start.failed
    prop:tags str,, e.g. machine:2323
    prop:state str,, ["NEW","ALERT","CLOSED"]
    prop:inittime int,, first time there was an error condition linked to this alert
    prop:lasttime int,, last time there was an error condition linked to this alert
    prop:closetime int,, alert is closed, no longer active
    prop:nrerrorconditions int,, nr of times this error condition happened
    prop:errorconditions list(int),, ids of errorconditions
  

Supported data types

Primitive data types

• int [integer]
• list [List/Array]
• str [String]
• list(int) [List of integers]
• list(dict) [List of dictionaries]
• dict [Dictionary]

Complex datatypes

• We have 2 types of models
  • ROOT models defined by [rootmodel:rootmodelname]
  • Child models defined by [model:childmodelname]
• Only child models can be referenced by root models
• You can't reference one root model from another root model
• You can't reference one child model from another child model

• you can reference a child model directly as in:

  • Example:

    [rootmodel:A] @index
      prop:value AA,,     # References another Child model (AA)
    
    [model:AA] @index      # Child model AA
       prop:value int,,
    
    [rootmodel:AList] @index  
      prop:value list(A),,   # References List of As
    

Support Time to live for model records

• Add the @TTL: seconds tag
• This means that each record will live for those seconds (unless updated)
• This works by using mongodb TTL functionality.
• Example

    [rootmodel:sessioncache] @TTL:432000
        prop:value dict,,
        prop:createdat datetime,,
        prop:lastupdatedat datetime,,
