Can grafana include the current timestamp in an alert notification's message? - grafana-alerts

I’ve a request to include the time when an alert was raised in the message body of the email for that alert.
I’ve checked out Create Alerts and Alert notification templating and it looks like it might be possible, but I can’t find any reference to any list of supported variables.
For reference, we're using Grafana v7.4.0 (c2203b9859) and creating an alarm off a cloudwatch metric query:
REMOVE_EMPTY(SEARCH('{"AWS/ApiGateway","ApiName","Method","Resource","Stage"} MetricName="5XXError"', 'Sum', 60))
So there's nothing in the results we can use for this, unless anyone knows of a way to pull the last timestamp out of one of the datatables ;)
What I’m trying to do is include something like this, in the email being sent out when this alert is triggered (although the actual date format doesn’t matter at all):
Alert raised at 2021-08-26T12:03
Thanks

How to transmit alert variables by E-mail message

I’m a newbie in AggreGate IoT platform and I’m trying to use its Alerts feature. I need to insert the name of the device that triggered the alert into the email message being sent.
I see some Alert Examples in the documentation but I can’t find the way to extract the context of the current device. I’ve tried to write the Alert Message expression like {env/context} or cell({env/context},"value") but it has no effect.
Please help me to make it work.
You need to send e-mail when Alert rises or deactivates, but with your own subject and message format.
Open "Automatic Corrective Actions" tab
Add action "Execution type" - Rise, "Action" - Send E-mail and click on "Parameters" field.
You should see e-mail sending parameters, such as Recipients, Subject, message, etc. You can write it by yourself or use bindings, in our case we will use bindings.
To get variables from alert we should use an expression for ex. "cell({env/value},"trigger")". This expression will return "Trigger message". You can get any variables that we have in Alert Event (see attached screenshot).
When you get variable value, you can use it with AggreGate expression language. For example, if you get cell({env/value}, "context") it will return context of the device for which this alert was set. You need to get name of this device, using context - you can write expression cell(getVariable(cell({env/value}, "context"),"genericProperties"),"name").

How to remove Ephemeral Messages

I'm trying to figure out the mechanism to post an ephemeral message to a user and then remove it and replace it with a message visible to all. Similar behavior to giphy in which the Slash Command shows an interactive ephemeral message and creates a channel message once the user decides which gif to send. I'm also curious about updating the ephemeral message. I assume this can be done by the response_url if we use an interactive ephemeral message.
I initially figured I'd just create a ephemeral message using chat.postEphemeral and then call chat.delete on it, but it seems chat.delete and chat.update can't be called on a message created using chat.postEphemeral.
The Slack message guidelines seems to suggest that a multi-step interactive flow should always be handled in an ephemeral way so that other channel user don't see all intermediate messages before the result but I'm having bad luck figuring out how to get rid of the ephemeral when done. Probably just being bad at reading but any help appreciated.
Edit with more details:
The documentation around using response_url and postEphemeral states
As you replace messages using chat.update or the replace_original
option, you cannot change a message's type from ephemeral to
in_channel. Once a message has been issued, it will retain its
visibility quality for life.
The message guidelines suggest:
If a user has initiated an action that has multiple steps, those steps
should be shown as ephemeral messages visible only to that user until
the entire action is complete to avoid cluttering the channel for
everyone.
Presumably, I should be able to create an interaction in which I first send an in_channel interactive message.
When a user initiates an action, I should be able to send them a series of ephemeral messages using the response_url and passing response_type: 'ephemeral' and replace_original: false?
A new ephemeral interactive message created this way will have its own response_url for making edits, right?
Once I am done with the interactive flow via ephemeral messages, I can modify the original interactive message using its original response_url?
Lastly, how do I get rid of the last ephemeral edit? Or do I just change it to something like "Workflow completed" and hope for the best? I'm asking because Slash commands obviously seem to have a way to essentially replace the ephemeral message for an in_channel message and I'm trying to figure this kind of workflow out.
I searched high and low on how to do this and finally came across the answer.
Your ephemeral message must trigger an action, i.e. button click.
Your response to the action must use the following body
{
'response_type': 'ephemeral',
'text': '',
'replace_original': true,
'delete_original': true
}
'delete_original': true is the key here, which as far as I can tell is not mentioned in any of the API guides, however it is present in the API field guide under Top-level message fields
If you wish to change the response_type of your message instead of deleting it, you must do so by first deleting the ephemeral message and then posting the same message with 'response_type': 'in_channel'.
In my use case I wanted to take an ephemeral message and repost it with the exact same message body as an in-channel message. I have not found a way to retrieve the content of your ephemeral message, so the best method I've found is to pass whatever necessary data spawned your ephemeral message in the button's value so that your action handler can read this data and dynamically recreate the message body.
In my case, this was the user input being used to perform a query. On the off chance that data in the database changes between the time the original ephemeral message is posted and the in-channel version is posted they will be different. You may be able to send a JSON string directly through this value field and avoid making additional database calls and running the risk of messages changing when posted to the channel. The character limit of value is 2000 so JSON passing is extremely limited.
Assuming you use the same code to generate this body when initially creating the ephemeral message and also when recreating it in-channel, you should receive the same body and essentially are able to change an ephemeral message to in-channel message.
Some ephemeral messages can be "soft" deleted/replaced but only when posted as part of a message with interactive features like buttons or menus. When a button is clicked or a menu selection made, you have a chance to instruct Slack to either "delete" the original message, or replace it with a new one. These docs detail using responses and response_url to accomplish that.
A message created with chat.postEphemeral that itself has no interactive features can never be explicitly deleted. Once it's delivered, it's like a ghost and will disappear following a restart or refresh.
Answering your bulleted questions in order:
Correct, you essentially start a new chain of interactivity with net new ephemeral message you post to that user
Each interactive message interaction will have its own response URL. The new ephemeral message won't have a response_url you can use until the end user presses a button, selects a menu item, etc.
response_url will eventually expire ("using the response_url, your app can continue interacting with users up to 5 times within 30 minutes of the action invocation.") If the original message is non-ephemeral, using chat.update is a better strategy for longer timelines. With ephemeral messages, it's more of a "do your best" strategy. They'll eventually get cleaned up for the user after a refresh.
I think you have a good handle on what's best. Personally, I think it's easier to kick off a new "in_channel" message by using chat.postMessage instead of as a chain effect directly from a slash command or interaction.
The Kotlin/Java version for this solution using the Bolt API as shown below
import com.slack.api.bolt.handler.builtin.BlockActionHandler
import com.slack.api.bolt.request.builtin.BlockActionRequest
import com.slack.api.app_backend.interactive_components.response.ActionResponse
import com.slack.api.bolt.response.Response
import com.slack.api.bolt.context.builtin.ActionContext
object Handler : BlockActionHandler {
override fun apply(req: BlockActionRequest,
context: ActionContext): Response {
val response = ActionResponse
.builder()
.deleteOriginal(true)
.replaceOriginal(true)
.responseType("ephemeral")
.blocks(listOf())
.text("")
.build()
context.respond(response)
return context.ack()
}
}
If you are using Python and Flask the following code should work when you respond to a button click in the ephemeral message:
from flask import jsonify
response = jsonify({
'response_type': 'ephemeral',
'text': '',
'replace_original': 'true',
'delete_original':'true'
})
return make_response(response, 200)

Copying a list of subscribed data in System center orchestrator

I'm using System Center Orchestrator 2012, and I have a generic error handler which is connected to all the activities in my runbook.
I have subscribed to a list of published data as a parameter in this error handler, which looks like this:
Activity Name : {Activity Name from "Monitor File"}{Activity Name from "Move file"}.......
What I need to do is copy this list of subscribed data and do a search and replace to change the Activity Name parameter to something else, say Error Message. Whenever I copy this list of variables, I get gibberish when I paste it
\`d.T.~Ed/{598EBDFA-BF5B-4B77-8156-E6FA6ECD0CE1}.Object.Name\`d.T.~Ed/\`d.T.~Ed/{6838D741-DF8E-4C25-8C28-D06A52F67D36}.Object.Name\`d.T.~Ed/\`d.T.~Ed/{D1D9BBE6-5AAF-4D8F-A98A-1A8BDD977E7E}.Object.Name\`d.T.~Ed/\`d.T.~Ed/{9EC92323-1B9B-4D06-88E9-A97BA525CF5A}.Object.Name\`d.T.~Ed/\`d.T.~Ed/{FAD32B4C-92CC-40BD-837A-4C5F22C2E018}.Object.Name\`d.T.~Ed/\`d.T.~Ed/{DFF7A110-ACFD-4377-AFEC-16B5BEC8BFF4}.Object.Name\`d.T.~Ed/\`d.T.~Ed/{139ACC4E-CF6D-4EEE-BD88-9DC1E0FC2038}.Object.Name\`d.T.~Ed/\`d.T.~Ed/{1484789C-BB37-4507-AD21-E367665E0BE6}.Object.Name\`d.T.~Ed/\`d.T.~Ed/{01EA8BD0-69C5-4959-86DB-29FAD34D144A}.Object.Name\`d.T.~Ed/\`d.T.~Ed/{A60C582B-5DD0-41F7-BB0A-B5D71C3B9ECB}.Object.Name\`d.T.~Ed/\`d.T.~Ed/{1FA1E2D6-813D-4A4A-A5CD-07EB2AD4AC9B}.Object.Name\`d.T.~Ed/
Is there a way to simply copy the text? If not, I will have to click on all the activities over and over again to subscribe to different types of data.
Thanks in advance
The gibberish you're seeing is how Orchestrator translates the published data and variables to the database guids. Copying this out will always translate to the DB guids, so there's no way to do a copy/replace with "activity name" for "Error Summary". You'd need to subscribe to each activity's data or look up all of the guids which probably wouldn't be easier.
Unfortunately, setting up the error handling process in SCOrch becomes tedious to be effective.
I use a separate email linked to each activity to give more information based on the error message. I don't like to use generic error emails with published data from multiple activities since it doesn't necessarily give all the useful information you need (or an end user will be able to understand).

Twitter Error Could not post Tweet

What could be this Error?
Could not post Tweet. Error: 403 Reason: Status is a duplicate.
actually this is a edited message .
i get error code as 403 and Reason as Status is a duplicate.
Twitter checks messages if they are duplicates of the previous and does not accept them a second time.
So for testing you need to generate new messages (=content) each time.
This is documented somewhere at Twitter, but you can also read about on other sites.
The status is a duplicate, probably running your script twice without changing the status message.
Delete your last status update via Twitter web and run the script again. Or include date('r') or md5(mt_rand()) with your status message to generate a different one each time the script is run.
I also had encountered the same error. what the twitter site says is that they check the messages tweeted and discard (refuse) them if they are same. Discussion here says to use different texts each time you make a tweet. Else use a different account for tweeting.
import time, os, random, hashlib, datetime
gettime = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")

twitterpost = "foo bar %s" % hash
api.update_status(status=twitterpost)

JavaMail: how to get new messages comparing with time-stamps

I'm trying to get messages after a certain time-stamp, the way I've coded it was suggested by another programmer in this site:
GregorianCalendar date = new GregorianCalendar();
SearchTerm newer = new ReceivedDateTerm(ComparisonTerm.GT,date.getTime());
Message msgs[] = folder.search(newerThen);
The issue is that I get all the messages since the date, not the specific time. I was wondering if there is some work-around to emulate this. I mean, for an instance, if I want to get all the messages since today in the midday I would get those messages spicifically and not those ones received in today's morning.
Thanks in advance,
EDIT:
A new thought concerning to this: perhaps some date manipulation could do the job. I mean, comparing the minutes in the timestamp and filter programmatically those messages that don't fit the criteria. I know it's not the best way, but it could work.
PS: I'm using IMAP and trying to get mails from gmail, but I guess it should work no matter what the mail-server is.
Unfortunately, no. In this case, the IMAP protocol is being used by the JavaMail classes, and IMAP's SEARCH command takes only dates, not times (see the SINCE and SENTSINCE criteria).
You could use the setTime() method to query for some specific time.
Example:
setTime(timeInMilliseconds)
