What types of data does Observer collect?
Observer collects metrics directly related to the performance of your ServiceNow platform. This performance-related information from ServiceNow's stats.do and xmlstats.do data is collected from the sys_cluster_state table's stats field. Additionally, sizing and growth metrics on specific system tables are collected to ensure that their growth is being monitored. The data collected does not include any customer-specific information.
How does Observer collect this data?
The Observer Application installs Scheduled Script Jobs that poll the sys_cluster_state table and execute aggregates on specific system tables. The data is collected into the Outbound queue table (psp_out_message), and a separate Scheduled Script Job queries this table to be POSTed to the assigned Perspectium MBS (Message Broker Service). The POST is done using SSL-enabled HTTP POSTS with the message broker service credentials supplied as HTTP headers.
How is data stored in Observer?
Observer stores its monitoring, alert, and trending data in a secure cloud database that can only be accessed by the Observer UI to render and display. No customer specific or sensitive data is stored.
