Starting with v6, the open-source version of Opensearch is embedded into Pulse. Opensearch is a search engine that helps Pulse store all the information about your TM1 application second by second.
This information can then be visualized with the Pulse Explorer. Pulse Explorer is powered by the open-source version of Opensearch Dashboards. Opensearch Dashboards helps you visualize and build your own dashboard on top of the Pulse Opensearch data.
Indices
Instead of a database, Opensearch is using indices. To learn more about Elasticsearch indices.
MySQL structure vs Elasticsearch:
- MySQL => Databases => Tables => Columns/Rows
- Elasticsearch => Indices => Types => Documents with Properties
Pulse Elasticsearch data is structured into 10 indices:
| Name | Description |
|---|---|
| pulse-alert-history | Information about Pulse Alerts |
| pulse-chore-process-history | Chores and processes history execution time |
| pulse-server-action-history | Information about Pulse actions such as stop/start services and disconnect users |
| pulse-server-state | All Server information such as server stats including all active threads |
| pulse-tm1-client-history | Information about the }Clients dimension |
| pulse-tm1-object-history | Information about all TM1 objects |
| pulse-tm1-server-log | Server logs information |
| pulse-tm1-session-history | All Sessions history |
| pulse-tm1-top | Information about all threads |
| pulse-tm1-user-history | User usage tracking (Excel, TM1 Web, Canvas and Pulse) |
Indices split by periods
To easier manage the volume data, the indices are split by periods (daily, monthly, yearly), indices that will contain lots of data are split daily (a new index is created every day) whereas indices that store less information are split monthly or yearly (a new index is created every month or year):
New indices are created daily for:
- pulse-tm1-top (disabled by default)
New indices are created monthly for:
- pulse-server-state
- pulse-tm1-server-log
New indices are created yearly for:
- pulse-alert-history
- pulse-chore-process-history
- pulse-server-action-history
- pulse-tm1-object-history
- pulse-tm1-session-history
- pulse-tm1-user-history
On the Pulse status page, you can see all indices per # of documents and size in the disk. In the example below, we can see there is one pulse-server-state index for 2020-12 (pulse-server-state-2020-12) whereas there are one pulse-tm1-top index per day (pulse-tm1-top-2020-12-11, pulse-tm1-top-2020-12-10…):
The DocumentType property
Some indices such as the pulse-server-state group different types of information such as information about server, instances and TM1top info. Pulse is using the DocumentType properties to group these different type of information.
Once the index selected, adding a DocumentType filter will reduce the fields to the relevant information:
Please find below the list of DocumentType per indices:
| Index Name | Document Type | Description | |
|---|---|---|---|
| pulse-alert-history | AlertLog | info about Pulse alerts | |
