Domotz is purpose-built to collect extensive data on your IT assets efficiently. By effectively managing and aggregating this data, Domotz provides valuable insights such as device status (online/offline), device uptime, network interfaces status, port mapping, and device-specific information. All of these features are already included in the Domotz default plan.
Moreover, Domotz can be configured to enhance its default monitoring capabilities. This can be achieved by using SNMP templates, Custom SNMP OIDs, TCP Sensors, and Integration Drivers.
Some Examples
Switch Monitoring
For network switches, you can activate the Network Interfaces SNMP Template to get detailed traffic statistics for each port:
Network Interfaces Overview
1. View the list of network interfaces with details for monitored devices.
2. Columns include Device Name, Interface, Type, Operational Status, Inbound Traffic, Inbound Errors per second, and Outbound Traffic.
3. Device Name column shows names like "Cisco Switch - SG350" and "Cisco Switch - SG250 - 8P."
4. Interface column lists specific interfaces such as "GigabitEthernet2."
5. Type column indicates the type of connection, shown as icons.
6. Operational Status displays whether the interface is "up" or otherwise.
7. Inbound Traffic and Outbound Traffic columns show data rates in bits per second (B/s) or kibibits per second (KiB/s).
8. Inbound Errors per second column provides error rates, if any.
You can also view a graph of each metric to see how it has changed over time:
Graph of Inbound Traffic on GigabitEthernet25
1. The graph displays inbound traffic over a period from October 4 to October 11, 2023.
2. The vertical axis shows the traffic rate in KiB/s ranging from 0.0 to 976.6.
3. A peak is annotated on October 10, with inbound traffic reaching 669.82 KiB/s at 13:18 MDT.
4. The last recorded change on this data was at 08:06 AM MDT on October 11.
5. The graph offers a zoom option with three selections: 1 day, 7 days (highlighted), and 1 month for viewing different time frames.
Server Monitoring
For servers, Domotz monitors hardware controllers (such as Dell iDRAC, HP ILO, Supermicro, and XClarity) or operating systems (such as Windows, Linux, and VMware) to keep track of servers health and performance.
In the following example, Domotz is monitoring the Physical Disks status to prevent any service disruptions on an HP ILO server:
Domotz monitors the disk status (along with many other disk properties) on an HP ILO server in order to prevent any service disruptions:
HP-iLO Physical Hard Drives Overview
1. The table lists information about monitored physical hard drives in an HP-iLO system.
2. Columns include:
- Device Name: Identifies the device hosting the drive.
- Index: Numerical identifier of the drive.
- Location (Bay): Indicates the bay number where the drive is situated.
- Status: Displays the current status, such as "ok."
- Condition: Provides a general condition overview.

- Age: Duration in hours, indicating how long the drive has been operational, shown as "18835 hour."
- Model: Model number of the drive, for example, "VK000480GWSRR."
3. Use the dropdowns in the column headers to filter or sort the information based on specific criteria.
Following, Domotz monitors the logical drives on Linux servers (specifically the disk space available on each partition), to prevent the disks from being filled up:
Disk Partition Information Overview
1. The table displays disk partition information with columns for ID, Percentage Used, Size, and Used space.
2. Under the "Id" column, partitions are listed as "/", "/boot", "/data/tiled_mdp/2", "/dev", "/dev/shm", "/run", "/run/user/0", and "/sys/fs/cgroup".
3. The "Percentage Used" column shows the percentage of each partition utilized, with notable usage for "/" at 91%, "/boot" at 59%, and "/data/tiled_mdp/2" at 89%.
4. The "Size" column indicates the total size of each partition.
5. The "Used" column details the actual used space in each partition in relevant units (G for gigabytes, M for megabytes, etc.).
6. Filtering and sorting options are available for each column via small input fields and arrows at the top.
7. A "Download CSV" link is provided for exporting the table data.
In this final example, Domotz lists all the VMs configured on a Proxmox host, along with their status:
Proxmox VM List Interface
1. Status is "RUNNING" with a sample period of 5 minutes. Variables consumed are 0.
2. The table below shows the list of virtual machines with columns for ID, Name, Status, and Memory.
3. There are sortable columns with filtering options for each field.
4. Virtual machines listed have IDs from 100 to 128. All show a status of "stopped" and memory allocated as 2048 MB.
5. A "Download CSV" link is available to export the data.
Service/Software Monitoring
We also allow you to monitor services such as Apache2, MySQL, Docker, etc.
Here is an example of how Domotz can be used to monitor the expiration of SSL certificates on a list of websites and hosts:
SSL Certificates Management Table
1. The table displays a list of SSL certificates with the following columns: Id, Issuer, Expiry, and Remaining days.
2. Under the "Id" column, domain names such as domotz.com, google.com, and portal.domotz.co are listed.
3. The "Issuer" column shows certificate authorities like Let’s Encrypt, Google Trust Services, and Sectigo Limited.
4. The "Expiry" column indicates the expiration date and time of each certificate.
5. The "Remaining days" column provides the number of days left until each certificate expires.
6. A "Download CSV" link is available at the top right to download the table data.
