It is with great pleasure that I announce that Server Configuration Monitor (SCM) 2019.4 is now generally available for download via the Customer Portal. Our dedicated and hard working engineers have delivered Linux support and other great features.
If you've seen enough and are ready to upgrade, we won't make you scroll to the bottom - here are all the links you need!
A few things to remember before you start your upgrade:
SCM already has great change monitoring of Windows servers and applications, and now you have the same visibility for Linux - monitor hardware, software, files and script outputs. And changes on your Linux servers show up right next to Windows:
What should I monitor? That's always a hard question to answer. SCM makes it easier by including four OOTB Linux profiles to focus on changes that impact the performance, availability, and security of your Linux servers and applications:
Monitor all the configuration files that apt uses as its sources. (/etc/apt/**/*)
Monitor the fstab configuration file. (/etc/fstab)
Monitor all of the configuration scripts used to control services. (/etc/init.d/**/*)
Monitor the configuration files for the init subsystem used to startup services. (/etc/init/**/*)
Monitor the configuration file for the initialization system. (/etc/inittab)
Monitor all the configuration files that are used by modprobe to manage the loading of modules during the system boot. (/etc/modprobe.d/**/*)
Monitor the list of modules to load at boot time. (/etc/modules)
Monitor the list of modules to load at boot time. (/etc/modules-load.d/*)
Monitor the configuration file that sysctl uses to change kernel parameters at runtime. (/etc/sysctl.conf)
Monitor the configuration files that sysctl uses to change kernel parameters at runtime. (/etc/sysctl.d/*.conf)
Monitor the file that yum uses for global configuration. (/etc/yum.conf)
Monitor the files that define the extra repositories yum can use. (/etc/yum.repos.d/*)
Monitor the files that store extra yum configurations. (/etc/yum/**/*)
Track changes to your file system block devices (via lsblk).
Monitor a detailed list of system hardware information for changes. List includes cpu (lscpu), general hardware (lshw), PCI bus (lspci), USB (lsusb) and SCSI (lsscsi).
Track the system's nodename, kernel-version, and kernel-release for changes.
Monitor for changes to the ports the system is listening on (excludes UDP).
Track changes to your file system mounts.
Monitor for changes in your network configuration, including the systems DNS name and aliases, network interfaces, hosts file, resolve.conf file and the nsswitch.conf file.
Track all installed packages for changes (both rpm and dpkg).
Monitor the services that are enabled on the system for changes.
If you've built your own profiles, you've had to deploy them before seeing what's returned. Not anymore - you can test elements right inside the product and rapidly iterate until you have them configured just right... then it's time to push out the new configuration and start monitoring. The new testing feature covers all element types - files, registry, and script outputs, and it even handles when an element returns multiple items.
Let's run a quick test of finding all the "conf" files in /etc/init. From the Server Configuration Monitor Settings > Manage Profiles, check a Profile and click Edit or View Details - I am choosing Linux Essentials. Then choose the * /etc/init/**/ element and click Edit or View Details at the top of the element list.
At the bottom of the Configuration Element Details, click Test. If you haven't chosen a Node previously, SCM will prompt you. Remember to pick a Node that matches the element type - running a Linux element on a Windows node generally won't work.
The result? I can see the three conf files found on the left, and the content for each file on the right. If these are the files you are looking for, you're done!
If I want to try it on another node, I simply click the node on the left and select a different node and see the results again.
Structural Diff Preview
For XML and JSON files, SCM will automatically use a structural diff when display the changes from one file version to another. This makes it easy for you to see the values that change regardless of structure changes (spacing, indenting, returns, etc). Below, SCM highlights just the changed values instead of the entire line and other noise... but you can flip back to regular diff if you prefer.
Content Comparison Improvements
When comparing two versions of files, SCM now has several improvements: Simplified breadcrumbs with links, less vertical white space so you can see more changes on the screen, and a rollover for the element to tell you more information on what you are looking at:
Assign/Unassign SCM Profiles in Manage Nodes
You asked to assign and unassign nodes to policies from the Manage Nodes page, and now you can!
If you haven't checked them out yet, here's a complete list of what changed in SCM 2019.4.
