How would maintenance impact data processing, etc. (i.e. for scale-up procedure)?AMIs must be upgraded every X months; how does that impact the application (Stream)?Have you seen any auto-scaling ? How does scaling down impact the application? Will data be lost or will it complete its processing before shutting down?Concerned about what happens to data in flow when instances are downLooking for details on public cloud use casesFor the infrastructure scaling sideAfter disaster recovery, how do they switch back to the original state?

How do i calculate the amount of workers i need if i am using AWS Fargate arm processors? I am looking at 7tb/day input and output to 2 destination which is a total of 21tb/day throughput.Thanks

I'm quite new to Cribl, so please forgive me if I've got some easy and/or dumb questions!The first thing the Palo Alto Pack pipelines all do is extract the host from an RFC3164 formatted syslog message with a BSD time format.Eval: host = _raw.match(/[A-Z][a-z]{2}\s{1,2}\d{1,2}\s\d{2}:\d{2}:\d{2}\s([^\s]+)\s/)[1] || hostOurs are sending in RFC5424 w/ Octet count framing (not syslog'y enough to know if that's RFC6587 or not), so the host extraction fails and ends up sending to splunk as the IP.With the desire to use the Palo Pack, what is the best way to handle this?Right now I created a pre-processing pipeline and attached it to my source. All it does is extract the host from the header. That way I don't have to handle it in every pipeline inside in the pack.Also, is there a reason you cannot connect a pre-processing pipeline to a source that's inside a pack? In this case, it would be nice to be able to package my

Dear all,Coming up with yet another question as I couldn't find similar from the history of available requests. I have created the HTTP RAW Source and able to push the data and process it in the pipeline. However, I have observed that when I POST the valid JSON format(all the attributes with double quotes), Cribl http source is parsing them into individual fields after the source process, and if the posted content is not JSON parsable, then the content is available under the key "_raw".As per my requirement, I would like to keep the input JSON object as is, since I was trying to validate the whole json with the schema stored in the Knowledge. If it's not getting parsed then I was able to run my use case as expected. In other case where the JSON is parsed into individual fields, I couldn't find any internal key which holds all these variable to format them back to JSON object to validate against the schema.Hence, reaching out for any sugge

I'm attempting to extract values from a JSON string field. However, it seems, that none of the below methods are working for referencing or obtaining the value using a JSON path or dot notation type of approach. I've even tried the "extract_json" function, but to no avail.KQL in Azure has the bag_unpack function, but I noticed this is not supported in Cribl Search.Below are my queries and results.| extend json=parse_json(_raw)| extend test1=_raw._raw.kubernetes.container_name| extend test2=json._raw.kubernetes.container_name| extend test3=json['_raw']['kubernetes']['container_name']| extend test4=extract_json("$._raw.kubernetes.container_name", json, typeof(string))| limit 10

Hello all,I have recently started working with Cribl and my question may seem to be easier one, however, I couldn’t find an option to do this in right way and hence reaching out for help.In one of my use case I am getting a json from source and my requirement is to check whether the attributes in the object are matching with some of the existing Regexes in Crible knowledge section. I was expecting something like below,For ex: To access Schema, we use C.Schema(‘Schema Name’).Validate()In the same way can we do C.Regexes(‘Name of the regex’).test()Please advise on this with any suggestions. Thanks in advance!

Is it possible for a member company to purchase a single license for the entire business group and share the license with the rest of the companies?

Can cribl stream carry out ldap queries to Microsoft AD and then save the AD information in a lookup table or something similar? I want to automate fetching AD information from AD servers and then feeding it to a SIEM like Splunk or Elastic.

Has anyone experienced system metrics crippling the 4200 port? What are some best practices or documentation to combat this and just setting configurations for system metrics in general?

Just upgraded a Stream cluster with 4.03. When performing the Commit to update the workers got "block timeout reached" message. Can be related to the amount of changes (195)? Is there any settings to change the timeout limit for updates?

What's the best way to reference a Worker Group Level Lookup File inside a pack? Would it be: $CRIBL_HOME/groups/<groupname>/data/lookups/LookupFileName.csv ?

I used a standalone test box to get my REST collector working like I wanted.  authentication, discover and collect worked great.  When I moved it into my distributed environment, it errors out but does pull in some events.  The discovery and collect phases are distrubuted across my 5 workers.  It seems like the authentication token may not be working properly when it runs on more than one worker?  I am guessing of course.  I get errors like 503 Service Temporaily Unavailable and 500 Internal Server Error.  This does not happen when I run it from my single standalone test server.  I may need some assistance trying to figure this one out.

I am getting this error in stream when trying to configure an IP address for a TCP source. I can't find any docs around this error.

I am running Edge Nodes on our EC2 instances. When reviewing internal fields from our File Collector sources, I noticed that there is alot of really useful data that our SREs use to investigate which regions & servers are experiencing issues during incidents. These include: - AMI image - Region - Availability Zone - Architecture - Public IP - Private IPI'd like to extract these internal fields as event fields that get sent to our destinations. What is the simplest way to do that?

For other users that have started pulling O365 activity logs using Stream instead of the Splunk app, have you noticed a discrepancy in the event counts? We consistently receive more events through the Splunk app than we do through the Stream source. The setup is exactly the same: tenant, app Id, content, and interval. We've even done comparisons into the data and have found events missing through Stream that were retrieved by the Splunk app. So it seems like Stream is either dropping some events or just not pulling all of them.We do have a case open with Cribl already but I'm wondering if we're the only ones seeing this. Has anyone else noticed compared the volume and noticed the same?

Does Cribl have any documentation for pulling Workday report logs?

Hi All,I am new to Cribl and trying to set notification via webhook for destination have back pressure or destination is unhealthy. But i am getting below error:"the notifications service is not available because a configuration file doesn't exist or the settings are invalid."

We installed the Cribl on our Linux server, and by default, it is user=cribl group=cribl.Our organization requires us to us a Service account to run configuration inside it.Question :Can we change the user and group ownership of the Linux directory of Cribl?And would it affect anything ?From user=cribl group=cribl.To user=svcacc_cribl group=svcacc_cribl

does anyone know how to 'unflatten' fields in Cribl Stream? For example: source.ip is a flattened field that I need to be modified as json: '{ "source": { "ip": "whatever" } }' Original message in Cribl Community Slack Message:https://cribl-community.slack.com/archives/C02A9EQV61J/p1698617495203379

I am currently setting an environmental variable in a Script collector using a JS Expression as follows: TEST_VAR = C.Secret("test1").valueThis works fine for some secrets, but not for others. In the latter case, TEST_VAR is equal to 'C.Secret("test1").value' instead of the actual value.I get the impression that the secrets for which it does not work have not yet been distributed to the workers in the group. Is this correct? Or is there something else wrong here.

With Cribl Stream what is the best practice for receiving windows logs?

I have a field that is nested. I can search with the full name without an issue but when I try to use it with project, I do not get any values back. I have tried to wrap the field with single and double quotes. That results in the value for the field to be the name of the field.The goal is to get a list of all the different values of the payload.comment.commentID field. What do I need to do to use the payload.comment.commentID field? dataset="MyDataSet" sourcetype="MySourceType" payload.comment.commentID=* | project payload.comment.commentID

What is the function of the NSSM.exe process that starts with Cribl Edge?

We're using AWS's c5d instance types which include NVMe instance storage for CRIBL_VOLUME_DIR, but we're also paying for a small EBS volume to host the configs in /opt/cribl.Is there a compelling reason to not just put CRIBL_HOME in the NVMe storage as well and have it pull down the config on startup?I came to this question because I was thinking about a scenario where we might shut down instances during low traffic times and how to handle being sure the CRIBL_VOLUME_DIR on the Ephemeral storage was formatted and mounted. It made me think, "If CRIBL_HOME was also there, then I wouldn't have to worry about CRIBL starting up without CRIBL_VOLUME_DIR being formatted and mounted".

I have an Event with no Splunk Metadata value within the events and i am trying to add new fields such as host, index,source and sourcetype . custom fields and i tried using an eval but no luck, how do i go about this ?
