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 ?

TLDR : JSON Collected from API, parsed through Pipeline, should have three JSON files in S3, but have two where one file have 2 JSON object appended, need help to find out the reasonHi All,At first, I want to say, no this is not an event breaker issue, as much as my understanding. Let me explain.I am trying to get some data from a REST Api endpoint using REST Collector. I am using discovery with Item list, and in the list, there are three values. In preview, three different events are also getting registered (sometimes, sometimes nothing is coming to the preview also).Now I am parsing this response using pipeline and putting the data in a S3 bucket using the router. I followed the documentation to configure the Destination as well as the pipeline and route.Now, I am setting up the schedular to run the REST Collector. Then, after each collection event, when I am checking my s3, there instead of having three separate JSON files for three separate events, there are two JSON files, one wit

Is the Cribl supporting SNMPv3?

Hi everyone, I have a use case atm where I have a lookup that contains a column of "allowed fields" for various sourcetypes, that is, the value for a given sourcetype is a common separted list of field names. At the end of my pipeline, I basically want to import this field list and throw away all fields in the data that are not contained in the list (because I'm finished with the normalization). Is there an easy way to do this? The serialize function has essentially the same functionality, when you import the parser you get a keep fields list. But how to do this without the parser?

How to connect my Bitbucket repository with Cribl?Question: When trying to push to a remote git repository created in Bitbucket under a project, I am getting the following error:This is working for other repositories created under a specific user, but not under a project in bitbucket.

Hi.I need to continuously read events from log file which is UTF-16 encoded. Is any way to convert collected data to UTF-8?Before that I used File System Collector which could use "Custom Command" option. Using "/usr/bin/iconv -f UTF16BE -t UTF8" solves the problem. But there is no such option for "File Monitor" source.

Hello, we are triying to setup a Splunk Search collector, against an on-prem splunk with a self signed certificate. Is it possible to disable certificate validation?

https://docs.cribl.io/stream/usecase-replay-s3/#which-format Starting in version 4.3, Cribl Stream supports replaying data that has been exported as Parquet, using either the S3 Collector or the Filesystem Collector.Meanwhile, the Azure Blob Storage and Google Cloud Storage Collectors support ingesting data in Parquet format, but do not support replay.I am glad to see that Parquet is now supported for S3 replay.  Is replay actually a feature in itself or just a technique implemented via a Source with different handling?How can Azure Blob and Google Cloud Storage collectors support ingesting but not support replay?

There's something about filters in an eval function (and probably other functions as well) that I either don't understand or that don't work as advertised. I have some events, all of them already have a field state. In some of these events, the value is a straight number. In some events, the field value contains an epoch time and a value, delimited by a pipe, e.g. 1696254765000|5.333333333333333. To get that value, I though I'd just use an eval and filter on events that have a pipe, like seen in the screenshot. However, that seems to remove the field for all events that do not match the filter (events that have just a number in state). I created a state_copy field to illustrate this: the top event only has state_copy, it does not have a pipe in the field value, and the second event has both state and state_copy.I would have expected the filter on the eval function to leave the top event untouched.I know I can solve it e.g. with a regex extraction instead of split() in eval, so I'm not

Hi all,Is there a cribl equivalent to Splunk’s rex mode=sed? I’ve tried replace_regex but I kept hitting a brick wall.I’m trying to take a timestamp with an indeterminate number of spaces and replace those spaces with a single space in a pipeline (using ‘eval’ function)Data looks like this:timestamp: “2023-10-03     09:29:00”Currently I’ve done the really hacky fix of extracting both the date and time and smooshing them together (eval date + ’ ' time)Thanks!

Hi All, I am having some issues when enabling a Smart Persistent Queue for a Splunk TCP source (TLS disabled). When the persistent queue is enabled the thruput drops by 2 orders of magnitude (from ~20k eps to ~200eps). The Cribl worker nodes are running on VMs, could this be due to the storage not being fast enough? If this is the reason why would the thruput drop so dramatically? Does enabling persistent queues on a source use much CPU?I don’t have any other source persistent queues enabled currently, but do have some on destinations that are working fine.
