Logstash aggregate

When I am using the aggregate filter in logstash to get the total sales of each product, for exampleis there a way to send the aggregated results to a different output and not line by line? Yes, you can drop the lines that are not aggregated and just keep the aggregations. See here for an example. If you need more details then you need to show us your input data and what your current aggregate filter configuration looks like.

Thank you!! We tried to implement the suggestion you gave. However, we have a large quantity of data and we want to read all the data and, in the end, show the aggregation results. We tried to maximize the timeout, but we never know when it will have the final results.

Here it is the code, if you can help us, we appreciate it. We just want to output the aggregation results. If I am reading it correctly, that elasticsearch input re-reads the entire index once a minute.

Is that right? The aggregate looks right, although a 4 second timeout is not very long. What problem are you having? Yes, we notice that schedule does not make sense here, we deleted. The problem is that logstash takes some time to get the results from elasticsearch, and if that timeout defined is higher that the time that logstash takes to read elasticsearch, the logstash will stop before showing any aggregation results.

If I considered a timeout like 10 seconds, the aggregation results will be repeated each 10 seconds. But if logstash stops before that seconds, the results will not appear as desired because logstash execution stopped as soon as read everything from elasticsearch. That will cause logstash to flush the map when it exits. We found the solution ordering the data from elasticsearch, because every time a new process came, the results were presented and the aggregations restarted.

Is it possible to aggregate results like process and total value and then for each process do a lookup to elasticsearch and an aggregate to get as final result a list of: process, processID, total value? I tried to do another aggregation like this by processID, but in the final result it only appears the first aggregation and an empty process.

I want to replicate each line of the first aggregation by the processID. Note that you can stash additional fields in the map, even if they are constant for a given task id, and they will get included in the aggregated event. We tried to create two aggregations, with elasticsearch lookup, but no success yet. Can you help us? I see you asked a question about getting elasticsearch to do the aggregation.

That is fundamentally a better approach that this. That said, if I have a csv like this. That will output the 4 lines from the csv, and then several seconds later output 2 more events having average set to 7.

Well, it could be done.Comment 3. In the first articleI mentioned some of the shortcomings of using the importer library, which I have copied here:.

logstash aggregate

I will be using the latest ES version, 5. We should be picking the equivalent Logstash version, which would be 5. Then, we need to install the JDBC input plugin, Aggregate filter plugin, and Elasticsearch output plugin using the following commands:.

This is because we are referring to these two files in the configuration using their relative paths. Below is the Logstash configuration file:. We run the Logstash pipeline using the following command:. We are using one worker because multiple workers can break the aggregations, as aggregation happens based on the sequence of events having a common country code.

We will see the following output on successful completion of the Logstash pipeline:. See the original article here. Over a million developers have joined DZone. Let's be friends:. DZone 's Guide to.

I will be using the latest ES version i. We should be picking the equivalent logstash version which would be 5. We need to copy the following into the bin directory to be able to run our configuration which we will define next:. Below is the Logstash configuration file:.

We are using 1 worker because multiple workers can break the aggregations as the aggregation happens based on the sequence of events having a common country code.

We will see the following output on successful completion of the logstash pipeline:. Categories: Elasticsearch. My problem is I need to add array of json and it is not happening with the above logstash.

Please find the below configuration file. Id AS i9FormId, emp. AccountId, emp.

IsInvalidEmail, sd.What is the best solution for one of the basic requirements in log's analisis. In that case, it's necessary to add a field called "Duration" on the "end events" and assign the subtract the time.

I wanna know the duration from the start to step1, from start to step2, and total duration. That's the solution if we want to calculte from the timestamp. The problem is that timestamp is assign by Logstash when an event comes. If we don't have a real time processing this isn't work. For that reason suppose an scenario like that. If we used Elapsed plugin the duration will be 5 miliseconds, but the real duration should be calculate by Real Time field, in that case the duration will be 20 miliseconds.

Rubytor You can overwrite the Logstash Processing Time with the real time for the event. Gnosis When you use the aggregate-filter you must set filter workers to 1. This isn't really nice. You should be very careful to set logstash filter workers to 1 -w 1 flag for this filter to work correctly otherwise documents may be processed out of sequence and unexpected results will occur. Maybe your shipper can do this. I depends on your usecase and infrastructure.

Image you have two logstash-instances with a load-balancer in front of them. How you would ensure that all Events flow to the same LS-Instance?

But you have to know one thing : computed duration is in seconds. If you want a more precise duration in milliseconds for exampleyou will have to use aggregate filter. In all cases, you must first use 'date' filter to set message date in timestamp field. Rubytor Gabriel April 15,am 1.

Gnosis April 15,pm 2. Rubytor Gabriel April 16,am 3. Just calculate the time between 2 event. The events has an ID to correlate them and a flag like start, step1, setp2, end. Thank you. Rubytor Gabriel April 18,am 5. Logstash Processing Time How can we do in that case??? Gnosis April 18,am 6. Gnosis April 19,am 8. Ok, thx a lot and how do you aggregate data without the aggregate-filter plz?

Rubytor Gabriel April 19,pm What about Filebeat?? I think it has it's own load balancer isn't it?? Up to me, the right solution for your need is to use 'date' filter and then 'elapsed' filter.In logstash, I am using grok and aggregate to extract the dataId value to combine multiple multiline events.

I don't want individual events to appear in elasticsearch - I tried event. Using the aggregate plugin to zip the messages back together is problematic because ordering is not strictly maintained; the multiline messages will need to be grouped on the Filebeat side before being transmitted to Logstash. If you are sending multiline events to Logstash, use the options described here to handle multiline events before sending the event data to Logstash.

Trying to implement multiline event handling in Logstash for example, by using the Logstash multiline codec may result in the mixing of streams and corrupted data. How is Filebeat configured? I have already taken care of filebeat and I'm getting multiple lines as 1 event. I'm trying to combine multiple of those based on an identifier. I'm able to group them but instead of getting only the aggregated one, I am getting 1,and so on. How do you know when an event is "done" and ready to be emitted?

Developing 1. Install dependencies bundle install.What am I missing? By default logstash will use about as many worker threads as there are CPUs. For an aggregate, that means different events get aggregated by different threads, so when you re-run a file it may get aggregated in different way.

If you are on a multi-CPU system and did not take action to prevent it then you are using multiple threads. You either use '-w 1' or '--pipeline. I am using the same logic on the other index and for some reason it doesn't aggregate all indexes. Unfortunately the sample is too big that I cannot post here. Any general tip that I can look to do the check list? Could it be because the original index has some issue like not all documents have the exact same fields?

Although they all have the field used by the aggregation. Here is how I call it:. FYI input index is originally created from nutch crawler if that is relevant. This topic was automatically closed 28 days after the last reply.
