Loki Configuration for MongoDB storage

Asked 2021-Jun-04 at 22:36

I was going through the loki documentation. And i came across storage section, where you can set the storage to be any DB/FileSystem/InMemory. Currently, i need to store the logs into MongoDB. How can i do it?

Loki Configuration

I don't see any configuration file to store the logs to MongoDB. Is there any reference/configuration file which could help me set these loki chunks and indexes to be stored in MongoDB?

MongoDB is not supported currently. Only a certain set of DBs are supported.

Storage options in Loki

The following are supported for the index:

Single Store (boltdb-shipper) - Recommended for 2.0 and newer index store which stores boltdb index files in the object store

Amazon DynamoDB

Google Bigtable

Apache Cassandra

BoltDB (doesn’t work when clustering Loki)

The following are supported for the chunks:

Amazon S3

QUESTION

Can you run Elasticsearch with Loki?

Asked 2021-May-17 at 15:52

I have elastic configured with Grafana and it has logs. I tried to query logs for the elasticsearch in grafana but did not have much succes. I went online to try to learn how to do so, but when I do it talks about Loki. Are you able to use Loki with Elasticsearch? Do not see a definite answer for this online.

...

ANSWER

Answered 2021-May-17 at 15:52

Using Loki with ES defeats the purpose of using Loki itself.

Loki prides itself on indexing only the metadata/labels of the logs and storing the actual log data separately in a compressed manner.

This reduces storage costs and leads to faster retrieval of data as there is less data to index as compared to the an ES index which indexes everything in a log line and worse still ,if the data is missing ,stores the index attribute as empty. (Almost similar to the diff between SQL vs NoSQL)

As of now, Loki does not support ES as the index store.

It uses two types of indices:- Labels and log chunks and stores them separately to be queried as and when required.

Label/metadata/index :- uses Cassandra,GCS,File System,S3

Data chunks:- Cassandra,BigTable,DynamoDB,BoltDB

For more info see Loki storage.

How to get GELF-Logs from local Docker daemon to Loki?

tl;dr:
Loki-docker-log-driver -> Loki : ✅ works.
Loki-docker-log-driver -> JSON Decode -> Loki : How?

For my local development, I run several services which log in GELF Format. To get a better overview and time-ordered log stream with filter functionality, I use the loki docker log driver.

The JSON log messages (GELF style) are successfully sent to loki, but I want to get them further processed so that labels are extracted. How can I achieve that?

If you have already sent the logs in JSON format to Loki, all you need to do is to select the desired log stream and pipe it to the "json" parser, like in the following example:

The config looks good, similar as mine. I would troubleshoot it with following steps:

Exec to docker container and check if the rules file is not empty cat /etc/loki/rules/rules.yaml
Check the logs of loki. When rules are loaded properly logs like this will pop up:

QUESTION

Grafana Loki does not trigger or push alert on alertmanager

Asked 2021-Apr-15 at 22:57

I have configured PLG (Promtail, Grafana & Loki) on an AWS EC2 instance for log management. The Loki uses BoltDB shipper & AWS store.

Grafana - 7.4.5, Loki - 2.2, Prommtail - 2.2, AlertManager - 0.21

The issue I am facing is that the Loki does not trigger or push alerts on alertmanager. I cannot see any alert on the AlertManager dashboard though I can run a LogQL query on Grafana which shows the condition was met for triggering an alert.

The following is a screenshot of my query on Grafana.

QUESTION

Get logs from kafka and send to loki

Asked 2021-Apr-14 at 09:27

hope you're all well during this pandemic.

I've got a kubernetes cluster running. The comunication between pods is done through kafka. It is currently logging to stdout only. No files. no kafka topic. This is obviously pretty bad.

I want to setup a grafana instance that lets me centralize all logs there. The storage would be Loki + S3

In order to do that, I found that many people use tools like Fluentd, FluentBit and Promtail, which centralizes the logs and sends them to Loki. However, I already have Kafka running. I can't see why I'd use some tool like fluentd if I can send all logs to kafka through a "logging" topic.

My question is: How could I send all messages inside the logging topic to Loki? Fluentd cannot get input from kafka.

Would I have to setup some script that runs periodically, sorts data and sends it to loki directly?

...

ANSWER

Answered 2021-Apr-14 at 09:27

I recommend you to use promtail because is also from Grafana and not use the kafka solution.

If you send the logs from your apps to kafka then you need to:

modify your apps to send to kafka instead of stdout
configure a log forwarder to send messages on kafka to loki (it can be fluentd)

And if you use one the normal proposed approach you need to:

configure a log forwarder to send messages from docker stdout to loki (you can use promtail default configuration)

But if you want to go for your solution with kafka in the middle there are some plugins of fluentd to configure kafka as input and output. https://github.com/fluent/fluent-plugin-kafka

I am new to Loki but all i want to do is to use it as simply as possible with helm.

I want to get the logs of my app witch is in kubernetes, but it seems that there is no instructions on how to do that. All I find is how to install Loki and to add it to Grafana as a datasource but I don't think that's what Loki is made for.
