HPA Portal sections Dataservers Rules

This block describes the rules that ran during the selected period. The rules are organized in 4 categories :

  • Trades rules
  • Messages rules
  • Transfers rules
  • Other rules

The category is determined by the technical interface implemented by the rule.

HPA Agent records each rule call and gives statistics on it :

  • Rule attributes
  • Number of calls
  • Average response time
  • Weight of the rule in relation all rules

dataserever rules

A filter can be applied using the button in the top of the block. dataserever rules

When a filter is applied, the weight is updated and compute only on the selected rules.

It’s also possible to filter rules using the Filter component: dataserver_rules_filter. It takes a regexp and will return all rules having attributes that match this regexp.

Rule attributes

The following attributes are extracted from the rule name, to quickly find the workflow that run it. Sometimes multiple workflow can run the same rules but only one can have performance issue.

  • Category
  • Processing Org
  • Product
  • Action applied to the trade
  • Type (custom or native)
  • Rule class
  • Method name

Enable or disable rule attributes through configuration

Any of the previously described rule attributes can be disabled through override_config/configuration_wkf_rules_attributes.yml configuration file:

attributes:
  - name: "CATEGORY"
    enabled: true
  - name: "PO"
    enabled: true
  - name: "PRODUCT"
    enabled: true
  - name: "ACTION"
    enabled: true
  - name: "TYPE"
    enabled: true
  - name: "CLASS"
    enabled: true
  - name: "METHOD"
    enabled: true

Disabling an attribute will simply remove it from the rule name. Since the number of attributes in the rule varies depending on the disabled attributes, each of these configurable attributes is prefixed, allowing to identify it.

Here is an example of rule with all attributes enabled:

Hpa|Rules|rt#Trade|po#CALYPSO_LDN|pr#Bond|a#NONE|t#NativeRules|c#com.calypso.tk.bo.workflow.rule.CheckPendingModificationsTradeRule|m#check

If PO and Product are disabled, the rule is stored as follows:

Hpa|Rules|rt#Trade|a#NONE|t#NativeRules|c#com.calypso.tk.bo.workflow.rule.CheckPendingModificationsTradeRule|m#check
