Roman Danyliw has entered the following ballot position for draft-ietf-ccamp-alarm-module-08: Discuss When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-ccamp-alarm-module/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- (1) Section 3.5, Alarm Life-Cycle. The text states that “A server SHOULD describe how long it retains cleared/closed alarms: until manually purged or if it has an automatic removal policy.” How is this retention policy described? Is that in scope for this document? (2) Section 4.2, Alarm Inventory. The text states that “A server MUST implement the alarm inventory in order to enable controlled alarm procedures in the client.” What is the expected server behavior if a client sends an alarm type not in the inventory (and it isn’t part of the dynamic addition process)? (2) Section 10, Security Considerations. It seems like “/alarms/alarm-list/alarm/set-operator-state” should be listed as an operation in the YANG model that presents a security issues (just like “purge-alarms”). Consider if one altered the operator alert state causing the alarm management procedures to miss an alert (e.g., setting an alert to “closed” before any action is taken). (3) Section 10, Security Considerations. I don’t know must about the implementations, but wouldn’t compressing alerts (per compress-alarms and compress-shelved-alarms operations) remove them from consideration by alarm management procedures? If so, these would be a sensitive operation that would need to be listed as the concern equivalent to the current text for purge-alarms. ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- (1) Section 1.1, Terminology, “Fault”. Consider expanding the acronym “MOS” (Mean Option Score?) (2) Section 2, Objectives, Consider s/X.733/[X.733]/ (3) Section 3.2, Alarm Type, Consider s/identity based/identity-based/ (4) Section 3.2, Alarm Type, Typo, s/standard organization/standards organization/ (5) Section 3.4, Identifying Alarm Instances, Consider s/were not really clear/were not clear/ (6) Section 3.5.2, Operator Alarm Life-cycle, Consider s/can also act upon/act upon/ (7) Section 3.5.2, Operator Alarm Life-cycle, Consider s/A closed alarm is an alarm/For example, a closed alarm is an alarm/ (8) Section 3.6, Root Cause, Impacted Resources and Related Alarms, Consider s/Different systems have various various/Different systems have varying/ (9) Section 3.6, Root Cause, Impacted Resources and Related Alarms, Consider s/In some occasions/On some occasions/ (10) Section 3.6, Root Cause, Impacted Resources and Related Alarms, Consider s/needs to represent an alarm that indicates a situation that needs acting upon/raises an alarm to indicate a situation requiring attention/ (11) Section 4.1.1, Alarm Shelving, The text states “The instrumentation MUST move shelved alarms from the alarm list (/alarms/alarm-list) to the shelved alarm list (/alarms/shelved-alarms/).” It wasn’t clear when these shelved alarms must be moved given the text. (12) Section 4.4, The Alarm List, The sentence, “The alarm list (/alarms/alarm-list) is a function from (resource, alarm type, alarm type qualifier) to the current composite alarm state” is missing a word/phrase. Removing the parenthetical remarks it reads a “The alarm list is a function from to the current composite alarm state” is does not parse. (13) Consider s/Life-cycle/Lifecycle/g
