Monitoring with SCM
- SCM 2024.1 supports monitoring on nodes running Windows Server 2008 R2 SP1 and newer and Linux kernel 2.6.23 or newer.
- SCM requires read permission to the monitored path for all file, parsed file, and registry profile elements. It requires execute permission for scripts.
SCM uses the SHA1 algorithm to compute a hash code while detecting whether a configuration item has changed on Windows and Linux machines. Although SHA1 is not an approved algorithm in FIPS mode, it is not used as a security function in SCM. Therefore, its use in SCM does not violate Federal Information Processing Standard (FIPS) 140-2 or the Cryptographic Module Validation Program (CMVP).

Important: SCM 2024.1 must run on SolarWinds Platform 2024.1. The time zone setting of the SolarWinds Platform server must be in the same time zone as the Azure SQL DB time zone (UTC). When deploying Azure SQL and creating a new user in the Configuration wizard, SA account credentials are required. When using Azure SQL for your database server, required tiers depend on whether you're using memory-optimized tables (In-Memory OLTP) supported in SQL Server 2016 and 2019 to improve the performance of transaction processing, data ingestion, data load, and transient data scenarios. |

*For SCM 2000, see the Scalability section for more information.
**Azure Storage Disk volumes are not your dedicated hardware. Consider using Azure Reserved Instances of storage disk volumes for SQL servers.
***SolarWinds recommends that customers with large environments or environments with frequent changes use DTU Premium Tier, vCore General Purpose Tier, or vCore Business Critical Tier (rather than DTU Standard Tier), as these tiers allow more IOPS.
Additional database space requirements
The amount of space required by SCM depends on the number of nodes being monitored, the frequency of changes, the number of configuration items being monitored, and the average size of a configuration item. Use the following examples to help determine your needs.
Number of nodes monitored by SCM | Number of configuration items per node | Average size of configuration item | Frequency of changes | Additional database space recommendation |
---|---|---|---|---|
1000 | 100 | 10.00 kB | Once per week, every item changes | 52 GB |
Once per day, every item changes |
365 GB | |||
50 | 10.00 kB | Once per week, every item changes | 26 GB | |
5.00 kB | 13 GB |
SCM database monitoring requirements
An ODBC driver is required. Drivers are automatically installed along with SCM. The following database versions can be monitored via out-of-the-box profiles using SCM:
- SQL Server 2019
- SQL Server 2017
- SQL Server 2016 SP1 or SP2
- MySQL versions:
- 5.7
- 8.0
- PostgreSQL versions:
- 9.4.25
- 9.5.20
- 9.6.16
- 10.11
- 11.6
- 12.1
There are no specific permissions needed by SCM for polling out-of-the-box database profiles. What is polled depends on what the user enters into the connection string field. SolarWinds recommends entering macros in the connection string to make use of credentials stored in the SolarWinds Platform. Credentials entered directly into the connection string are stored in plaintext.
Scalability
A SolarWinds Platform instance with SCM installed can process up to 280 changes/second combined. If you expect to have more than 1,000 agents per polling engine, you need an APE.
See also Scalability Engine Guidelines for SolarWinds products.
Adding an APE enables you to collect data at a rate or volume beyond the capacity of a single SCM server. You can also use APEs for organizational purposes, so server configurations at each specific site are monitored by site-specific APEs.
As of SolarWinds Platform 2022.3, APEs are updated to a new, licensing-controlled version.
For SCM, the additional polling engine is included in the product license, so install an APE. During the evaluation period, you will see an APE evaluation license in the License Manager. After the evaluation period, no extra license will be displayed in the License Manager because it is included in your product license. You cannot stack these licenses.
By selecting Additional Polling Engine for Server Configuration Monitor during the installation of an APE, that included APE can poll only servers that are monitored with SCM or other products specifically mentioned as compatible with the APE during the installation.
