Johnny Suleiman - PeerSpot reviewer
Scalability is a key feature as it allows easy scaling of the platform without downtime
OpenSearch is used as a search engine for specific logs, mainly in e-commerce and monitoring the logs themselves. It is very valuable for e-commerce, enabling data analysis on application logs and customer behavior, and can be integrated with other services, including AI and machine learning…
Volodymyr Bondarchuk - PeerSpot reviewer
Integrations enhance monitoring but problem-solving proves challenging
Different types of integrations with various sources are the most helpful and useful features of Grafana Loki that I found for myself. As part of Kubernetes technology, I noticed benefits from using this product such as availability, configuration balancing, high availability solutions for high performance, and failover clustering. It provides a clear picture about the state of the system and gives needed information for taking action and quickly fixing problems.

Pros

"It's a good log management platform. In terms of infrastructure management, it's good."
"The stability of the product is good."
"This service already sorts data like vectors. They have classified the storage pre-defined."
"It enables us to efficiently search and retrieve our event data, offering us a versatile approach to locate specific information within these logs."
"The customer service is excellent, rated nine out of ten."
"I would definitely recommend Amazon OpenSearch Service to other professionals due to its fast and reliable search capabilities."
"In case there is a failure, Elastic manages everything well, and there no major downtime."
"Amazon OpenSearch Service has enhanced our organization's ability to store and search large amounts of data efficiently."
"I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."
"The product's most valuable features are ease of installation, management, and reporting. It has an efficient ability to set thresholds for alerts, as well."
"Grafana Loki is easy to monitor and detect errors."
"The most valuable part of Loki is the ability to filter logs by keywords and devices."
"Loki significantly saves time in troubleshooting by quickly pinpointing network issues."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
 

Cons

"They can enhance data visualization."
"It would be beneficial to have some level of customization available in the managed service, tailored to the specific use cases of the end users."
"One improvement I would like to see is support for auto-scaling."
"I would say that, basically, the configuration part is an area with a shortcoming...Some upgradation is required on the configuration side so that we can get to use it."
"We faced documentation challenges during integration after migrating from Elasticsearch to Amazon OpenSearch Service. Better documentation on integration, query handling, and a more user-friendly UI could enhance the product."
"Amazon Elasticsearch can improve the bullion in the near search and the ease of integration with Kibana. Additionally, there could be more flexibility in the configuration and documentation."
"One glaring issue was with our mapping configuration as the system accepted the data we posted, but after a few months, when we attempted complex queries, we realized the date formatting had become problematic."
"I want to see a new feature in Amazon Elasticsearch Service that allows users to create default filters for filtered levels."
"I do not see any areas for improvement at the moment."
"The solution's scalability depends on the team managing the Grafana instance."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"The Docker container partition feature needs improvement as they do not reuse the space and goes into a pending state."
"We face some bugs when we install the latest version of Grafana Loki."
"We encountered certain limitations when it came to alerting, particularly when dealing with specific data sources."
"Visualization-wise, Grafana Loki's dashboard looks a little outdated compared to other open-source visualization tools like Chronograf."
"My main concern is the recommended production-grade setup. They suggest using tools like Tanka or Jsonnet. They should simplify the process to increase adoption."
 

Pricing and Cost Advice

"The solution is not expensive, but priced averagely, I will say."
