dmtf/redfish-event-listener

The Redfish Event Listener is a lightweight HTTPS server that can be deployed to read and record events from Redfish services.

redfish-event-listener's Issues

Does not support EventFormatType and therefore cannot subscribe to metric reports.

REST events not logged with HPE iLO -observed only with Latest available DMTF Listeners

Observing with Latest available DMTF event Listener , when Created the subscription with HPE iLO5 or iLO6 IP ... Initially only few events gets logged .And same single REST event is logged Multiple (around 3-4) times , No any further events getting logged in Listener even there are n-number of state changes. This issue was not observed with Previous DMTF event listener code RedfishEventListener_v1.py , build during 11/26/2021 Time Frame.
In the debugging, Encountered Error as ,
resteven: Event dispatch failed. HTTP:204 for Payload:

{"@odata.context":"/redfish/v1/$metadata#Event.Event","@odata.type":"#Event.v1_2_9.Event","Events":[{"EventId":"8f924994-902e-695f-e40f-c64e4d1a6d5c","EventTimestamp":"2023-05-24T18:24:01Z","EventType":"ResourcFYI(W) resteven: Subscription: 6, Error: 9, HTTP code: 204 Response:

Observing the Event Listener code is returning 204 response. In our iLO code, iLO keeps on retrying till it received 200 OK from Listener . As the Event listener code is returning 204 response consistently for REST events dispatched to Event Listener with POST operation , Connection is getting closed after multiple retires (specified in "DeliveryRetryAttempts") , failing to log further upcoming n -number of REST events

Would need fix from DMTF Event Listener code for this issue, for receiving REST events/Alerts from HPE iLO successfully.

Sample few REST events logged in Listener before closing connection after multiple retries ,
Redfish Event Listener v1.1.3

Server subscription sends deprecated Property EventType deprecated in EventService v1_3_0+

The subscription function attempts to send property EventType, which was deprecated in EventService v1_3_0, so may cause the request to fail on DSP0266 version 1.6.0 compliant servers.

def PerformSubscription():
    global ServerIPs, UserNames, Passwords, Destination, EventTypes, ContextDetail, Protocol, SubscriptionURI, verbose
    ServerIPList = [x for x in ServerIPs.split(",") if x.strip() != '']

    PasswordList = Passwords.split(",")
    AttributeNameList = ['Destination', 'EventTypes', 'Context', 'Protocol']
    AttributeValueList = [Destination, EventTypes, ContextDetail, Protocol]

{"@Message.ExtendedInfo":[{"MessageArgs":["EventTypes"],"Resolution":"Remove the unknown property from the request body and resubmit the request if the operation failed.","MessageId":"Base.1.6.PropertyUnknown","Severity":"Warning","Message":"The property EventTypes is not in the list of valid properties for the resource.","@odata.type":"#Message.v1_0_8.Message"}]

Event listener fails to receive redfish event immediately

Redfish event listener is being ran on local machine. A listener is receiving each event after 30s.
System(server) log was analyzed, observed that system was failed to receive a response and enter into retrial mode. Identified an issue about connection. After each response from listener to system(server), connection must be closed and a signal for closing a connection should come form listener.
I checked in POST method section, https://github.com/DMTF/Redfish-Event-Listener/blob/master/RedfishEventListener_v1.py#L122-L123, Status code is sent as response only. Response need to has "Connection: close" message as general-header with status code. I applied the change to this file in my local machine and tested, a connection was closed successfully after response complete.

Applied changed in RedfishEventListener_v1.py:

Event Listener receiving same Redfish events

DMTF Redfish event listener is being ran on local machine. My observations are followed below.

Observation:

• While receiving events from Redfish event listener it observed that system was repeating the same events after 1-2 mins.
• Because it gets into retrial mode(DeliveryRetryAttempts) due to absence of content-length header and json response.
• Identified an issue about the response that is sending from the Redfish event listener does not contain the content-length header and the json response.

I checked in POST method section, https://github.com/DMTF/Redfish-Event-Listener/blob/master/RedfishEventListener_v1.py#L122-L123, Status code and "Connection: close" are sent as response only.
If Response have "Content-length: "+str(len(bodydata))" and json.dumps(bodydata) message with status code and "Connection: close" with these changes, the events are not repeating it's working fine.

 res = "HTTP/1.1 200 OK\n" \
       "Connection: close\n" \
       "Content-length: "+str(len(bodydata)) + "\n" \
       "\n" + json.dumps(bodydata)

If i'm wrong. please let me know.

Fail to create a subscription

from tag 1.1.1, start from execution file, it will appear below error

Traceback (most recent call last):
File "/root/Redfish-Event-Listener-1.1.1/RedfishEventListener_v1.py", line 260, in
my_ctx.login(auth=logintype.tolower())
AttributeError: 'str' object has no attribute 'tolower'

not sure if "tolower()" function should replace as "lower()", or we should use specific python version to support it ?
after made simple test to replace it to "lower()", as result, it is workable. thanks your attention

Event listener fails to receive alternate events

I am running Event listener on a machine. Event listener consistently fails to receive alternate event.

Here is my Event listener output.
server sent 3 events with ids 5,6,7 but listener recieved only 5 and 7 where as 6 is not received.
this observation is consistent even with 100 events, every alternate event is missing

"SubsciptionDetails" should be "SubscriptionDetails"

In the config file and the code, SubsciptionDetails is used with the typo.
It should be changed to SubscriptionDetails

Unsubscribing and SSE Eventing

Is there any plan to support testing for unsubscribing and SSE eventing?

Does not support IPv6 listening

Currently this only binds to IPv4 sockets. If an IPv6 address is provided as the listening IP the code crashes.

Propose to add Redfish Event validation against Event schema

Event listener currently doesn't have the capability to flag errors for below conditions:

1. Event data is not compliant to the Event schema
2. Numbers of MessageArgs is not aligned with the numbers specified in the Message Registry

Does it sound like a good idea to add these checking's to the event listener?

Welcome other thoughts as well, thanks.

StatusCode at RedfishEventListener_v1.py#L224 seems incorrect

At RedfishEventListener_v1.py#L224, the value of StatusCode will be returned.

StatusCode = """HTTP/1.1 200 OK\r\n"""

However, in RFC7230, HTTP-message is defined as follows:

HTTP-message = start-line *( header-field CRLF ) CRLF [ message-body]
start-line = request-line / status-line
status-line = HTTP-version SP status-code SP reason-phrase CRLF

It seems that the tool should return status-line + CRLF and therefore StatusCode should look like the following:

StatusCode = """HTTP/1.1 200 OK\r\n\r\n"""

Need support for non-SSL Events

Currently Redfish Event Listener only supports SSL POSTs of Redfish Events. Request support for non-SSL Events sent by Redfish Mockup Server. Whether Event Listener is listening for SSL or non-SSL POSTs should be configurable in the config.ini file.

subscribing more than one server

It is not possible to subscribe more than one server together.
They need to be subscribed one by one, before merging them in the ServerIPs part of the config.ini file

Https receiving throwing error

Hi DMTF,

I am getting below error while destination is configured with https://:port

The subscription is successful but when I send the event from BMC it is failing.

Please provide the info where I can disable the https handshake but still I should be able to receive the https message.
