New AWS Region discovery and Secure Token Service capability

Centreon Amazon Web Services monitoring is made of tens of Monitoring Packs to constantly discover and monitor your Cloud infrastructure and services.  As a monitoring administrator, you need to embrace the dynamic nature of cloud assets and make sure that getting a 360 view of the health of these assets doesn’t imply making concessions on the security. That’s why we introduced two major enhancements to the way we discover and monitor AWS Cloud services. Amazon Secure Token Service With the Amazon STS feature, use temporary credentials by making deploying a poller as an EC2 instance a poller inheriting privileges from its associated IAM role. You don’t need to store sensitive access and secret key anymore to scrape metrics from Cloudwatch, temporary ones are created upon request when a check is performed. From now, all AWS Packs support the AWSASSUMEROLE macro allowing you to comply with AWS security recommendations and get rid of hardcoded AK/SK pairs.  Note that your host discovery module must be up to date to use this new capability.  Amazon Unified discovery Until today, if you used 11 AWS services across three regions, you have to create 33 separate discovery job definitions… Say goodbye to all this pain and time wasted: you can now only stay at the region level and create only 3 definitions thanks to the new AWS Cloudwatch Discover Pack!  Indeed, you can leverage the STS mechanism through the provider as access and secret key are not mandatory when using this meta-provider.  Discover hundreds of assets in seconds: Exhaustive documentation is available here and we’re open to any feedback or comment!

New! Leveraging VMWare tags in your Host Discovery, a step-by-step guide

New metadata available within your discovery rules How to set it up Leverage Tags to filter the discovery resultA few months ago, we added the capability to use VMWare Custom Attributes metadata as attributes when discovering ESX and Virtual Machines using the VMWare daemon and plugins.  These Custom Attributes generally help vCenter administrators to logically group and organize their resources within the vCenter. One specific thing about these attributes is that they are user-defined, which means that every user can set their own key/value pairs. As an admin, you need complete control over a resource metadata value so that it can be a piece of reliable information to organize your CMDB, manage permissions, or provision your monitoring efficiently!  New metadata available within your discovery rules Based on your feedback, we decided to make available new metadata commonly defined at your ESX/vCenter level: Tags indeed! The goal behind it is to align Centreon capabilities with those of the standard automation tools like Ansible and make your life easier by adding some magic to your operations:  Provision your VMWare resources using your favorite automation tools, tag your resources with any key/value that is relevant to your use case Discover these resources thanks to Host Discovery Leverage associated metadata to organize your monitoring (groups, categories) or apply different templates (apply OS or Application template to each resource associated with a given tag).  You can read more about Tags and Custom Attributes on the VMWare blog. Let’s see how it appears in the VMWare UI from a user perspective (it may differ depending on your version). We will focus on the centreon-central-vm.  Those tags will help apply a template, filter out some results, or assign a specific dimension. Categories aren’t managed (yet), but we would love to hear from you in the comment section if you have such a need.  How to set it up You must have a Centreon version > 21.04 and Centreon VMWare daemon > 3.2.5 to use this feature.   To benefit from tags management, you will have to perform several actions. It will not take you more than five minutes!  Update your VMWare daemon, and restart it  On poller(s) executing the centreon-vmware daemon, update the package:  RPM Distributions:     yum update centreon-plugin-Virtualization-VMWare-daemon Debian 11:    apt upgrade centreon-plugin-virtualization-vmware-daemon Restart the daemon: systemctl restart centreon_vmware Update your Monitoring Pack(s) Upgrade your VMWare Monitoring Packs on your central server, providing Host discovery rules.  If you are using an offline license, upgrade packages first:  RPM Distributions: yum update centreon-pack-virtualization-vmware2-vm centreon-pack-virtualization-vmware2-esx Debian 11apt upgrade centreon-pack-virtualization-vmware2-vm centreon-pack-virtualization-vmware2-esx > If you want to monitor VMWare resource for the first time, substitute update/upgrade by install in the commands above. Go to the ‘Configuration > Plugin Packs” menu and click on the VMWare ESX and VMWare VM Packs to install.   Create or update your Host Discovery job definition Go to “Configuration > Hosts > Discovery”. If you create a discovery job for the first time, check out this documentation before going further. If you update an existing one, just click on your current job definition and add --tags within the ‘Extra Options’ field:  Note that we increased the timeout to 30 seconds as the API for tags differs from the one used for monitoring, and calling it for each of the discovered assets introduces some extra processing.  Leverage Tags to filter the discovery result Once your job successfully runs, you should see the result of the discovery on the right. Here I discovered 136 virtual machines:   To leverage tags on my ‘centreon-central-vm,’ we can use three kinds of mappers:  Exclusion, to exclude all VM with a tag with monitoring as a tag description and for which the tag name doesn’t match enabled.    Template, to apply the OS-Linux-SNMP-custom template to VM having OS as a tag description and linux as a tag name.    Host group, to create/assign the prod host group to every VM having the tag name prod:  The final result before hitting save will be similar to:  From 136 results, I was able to filter on the very specific VM interesting me:   Enjoy! As usual, share your feedback in the comments to help us continuously improve this feature.

What's new with Azure cloud monitoring this september?

Monitoring Packs refactoring 🔧 Enhancements 💡 New Monitoring Packs - Community powered 🚀Monitoring your Azure deployments is key to observing how your cloud migration goes and/or how Microsoft IaaS/PaaS platforms behave over time while running your applications. This summer, we’ve brought several enhancements to Azure monitoring to align all probes and packs to the latest best practices. That might impact your current configuration so be careful when updating your Monitoring Packs to avoid false positives.  We’ve also added some minor improvements to existing Packs our customers expected to have a better vision of what’s going on in detail.  Monitoring Packs refactoring 🔧 Here is the list of the Packs that benefit from the latest code optimization and documentation layout:  Azure Virtual Machine Azure Express Route Azure SQL Database Azure SQL Server Azure Virtual Network Azure VPN Gateway  Enhancements 💡  Last month, we released new tenant discovery host discovery rules to reduce the number of jobs to configure to discover all your Azure assets (Azure Discover Tenant Discovery). To deal with a huge number of assets (more than 20k), we introduced a new –select-type option to reduce the scope of the discovery and ignore resource types that are irrelevant.   A new lookback option in the existing Items check has been added. It allows you to define how far in the past the plugin will look for failed VM/Vault backup allowing you to get rid of very old failed backups for which an alarm became irrelevant A new Replication mode is added to add broader support for recovery points. You can monitor your site/vaults' replication and failover health.   New Monitoring Packs - Community powered 🚀 Thanks to an open-source contributor, two news packs have been added, and we love it! They will enable you to watch over your Azure objects allocation and financial spending carefully. Azure Active Directory: leveraging the Microsoft Graph API and helping you track the evolution and quota usage of objects configured on your Cloud Azure Directory. An explanation of how important it is can be found here.  Azure Management Costs: connect to the consumption APIs provided by Microsoft to track down the financial spending for a given subscription or resource group. Very helpful to control and optimize your cloud costs over time! Use the embedded service discovery rule to add services without effort easily!   All these enhancements and new capabilities are our this September. Make sure to check it out!

Monthly Monitoring Packs releases - July 2022

Hello fellow watchers, Here is the content of the July connector release, hope you’ll enjoy it. Feel free to drop your feedback in the comments!  New Packs  Azure Classic Storage & Storage Accounts: this month, we’re adding new modes and discovery capabilities for each type of Azure Storage account mode (legacy or v2). Host Discovery now offers the right template that includes the supported metrics only.  Linux Node Exporter: This new pack is close to a turning point. At the very least it highlights the gap we want to bridge between dev, ops, and monitoring teams. By supporting the monitoring through Node Exporter for Linux servers, we allow these teams to speak the same language when it comes to metrics collection. Enhancements Amazon SNS & SQS: Discovery rules are now at the host level rather than at the service level. It makes these Packs easier to use and your monitoring well organized.   AWS Billing: To align how we discover from AWS today, and to prepare for something bigger, we’re refocusing the discovery feature from the service  to the host level. It allows leveraging the power of this pack in a few clicks!  AWS Lambda: You’re building serverless deployments and your application heavily relies on AWS on-demand functions? You can now discover each of these functions and make it a dedicated host. Dynatrace Rest API: Codebase upgrade to use the v2 API, and bring new monitoring capabilities: Apdex, Availability, Events… You can now reflect your Dynatrace logical organization by filtering problems by management zone for better alert management.  Linux NRPE3: Add objects (commands, templates, etc.) to monitor your Linux server’s NTP synchronization using the NRPE3 Protocol.  Nmap CLI: Add WSMan port to the scanning range so you can leverage this new way to monitor Windows environments and combine it with Nmap discovery capabilities.  Nortel Standard: Check your Nortel devices’ stack status.  Enhancements impacting current configurations   PostgreSQL: We added new services: Bloat and Collection. As the code base was quite old, we reworked it to fit with the new metrics naming system. It will break some configurations and change the way graphs are displayed.  Bugfixes  Active Directory WSMAN: Fix typos in Active Directory WSMan commands. AWS ELB: Add missing classic and applications ELB Discovery rules in the latest Centreon releases. Azure Database for MySQL: Fix typo in ‘serverlog-usage’ option label. Please check that thresholds are correctly set after the upgrade as macros’ names are changing!  Ruckus ICX SNMP: Fixing macro name in Ruckus ICX Memory service template to fix thresholds.
