What is included with Stackhero for Graylog?
We include OpenSearch, MongoDB, an email server (unlimited!) as well as a reverse proxy.
You don't need to add any other services, Graylog is ready to be used directly.
What is the limit of concurrent connections?
Unlike traditional cloud providers, Stackhero allows unlimited concurrent connections!
The power of your instance is entirely dedicated to you. You can use as many connections as you want as long as your instance can handle them.
Are some plugins included?
We have included official plugins from the Community Edition as well as the
Slack/Mattermost and
Telegram Alert plugins.
If needed, we can potentially add other plugins. You can contact us, and we will review your request.
How long are the logs retained?
You can keep your logs as long as you want.
As long as the disk space of your instance supports it, there is no limit!
How is log retention managed?
You can configure the retention of your logs with great precision using the Graylog interface.
For example, you can choose to keep the logs for the last 365 days, retain the last 200 million messages, or limit the occupied space to 400GB.
How many logs can be stored on an instance?
Graylog uses a journal that acts as a buffer between the time it receives the logs and when they are stored in the OpenSearch database.
This journal can occupy up to 7GB of disk space on your instance.
Additionally, Graylog, MongoDB, and OpenSearch require disk space to function properly.
Since OpenSearch has a protection mechanism, the database will automatically switch to read-only if the disk has less than 7GB of free space.
This is why we advise you to configure your retention to always have 15GB of free disk space on your instance to ensure its proper functioning.
Is it possible to connect to the instance using SSH?
Since Stackhero provides managed services, SSH access is not available. For any installation needs, please contact support to explore possible solutions.
Is it possible to restrict access based on IPs with a firewall?
Absolutely! Your instance has its own firewall where you can decide which IPs have access to which port in 2 clicks.
What cloud providers are used by Stackhero?
We created our own cloud software solution, making us completely independent from cloud providers. We deploy this innovative solution directly on bare-metal servers, providing you with incredible performance and stability.
Where is the data hosted?
Stackhero is a French company operating under European and French laws.
Servers are located, depending on your choice, either in the European Union (France) or in the USA.
Backups are stored in the European Union.
What is the software infrastructure?
Your service is composed of multiple subservices. All of them are running in containers, within a virtual machine, totally dedicated to you.
This VM is totally private and isolated from other clients, offering a highly secured environment with very high-performance.
It is hosted on a bare-metal server running Stackhero DC OS, our own Linux distribution.
What about disk performance?
We use disks physically plugged to your instances.
We don't use network disks, contrary to traditional cloud solutions, that are slow and expensive.
This way we ensure best performances and exceptional IOPS.
What is the atomic backup system?
The problem with traditional backup systems is that files are saved at different times interval.
Let's say you have 2 files, a.txt and b.txt. Your backup starts at 9am and it finishes at 10am.
The file a.txt will contain data from 9am and b.txt will contain data from 10am.
This is traditional in backups systems and is a big issue leading to consistency problems.
This is why we developed an in-house backup system that takes an atomic image of your instance at a precise moment.
Atomic in a way that we can guarantee that all files from the backup have been taken exactly at the same time.
If your backup starts at 9am, all files will have data from 9am. You have a perfect consistent and reliable backup.
Are backups encrypted?
Backups are first transmitted to a dedicated server, which verifies and validates the data. Once these checks have been approved, the backups are encrypted and archived.
Encryption uses ECDH and Curve25519 as part of the OpenPGP protocol, with a unique key generated for each backup.
How does billing work?
At the beginning of each month, our system computes how many hours your services were up and a detailed invoice is created.
You receive a single monthly invoice, containing all your services, clearly explained and easy to understand. Your accounting department will love that!
What certifications does Stackhero hold?
The primary mission of Stackhero is to provide a platform that is easy to use, extremely reliable, and highly secure.
A key element in achieving this mission is the annual attainment of the ISO 27001 certification, a globally recognized quality and security label.
This certification, awarded following a rigorous audit conducted by an independent external body, attests to compliance with the strictest international standards in information security.
