Abstract: Distributed tracing is applied during an upgrade from a first management appliance to a second management appliance. The distributed tracing method includes generating a parent span that encapsulates states of the overall workflow, including a span context that contains a trace identifier and a span identifier, and generating a plurality of child spans. Each child span encapsulates states that represent a piece of the workflow and contains a reference to the parent span context. The states of the child spans include an error tag that indicates whether the piece of the workflow associated with the child span executed with an error. Because child spans may be generated for a piece of the workflow that is executed by a service running in the first or second management appliance, the span context for the parent span is persisted by the first management appliance and replicated for use by the second management appliance.

Abstract: In an example, a gateway device includes a gateway application to receive a hypertext transfer protocol (HTTP) request from a client device and transmit the HTTP request to a server. Further, the gateway application may receive an HTTP response from the server responsive to the HTTP request and determine whether a size of a response body of the HTTP response is less than a threshold. In response to determining the size of the response body is less than the threshold, the gateway application may determine whether the response body includes a predefined sequence. Further, in response to determining that the response body includes the predefined sequence, the gateway application may parse the response body to determine whether the HTTP response is an error response of interest. In response to determining that the HTTP response is the error response of interest, the gateway application may manage the HTTP response.

Abstract: One or more embodiments provide techniques for querying a database having information contained therein that is associated with one or more virtual machines executing on a host. A management agent receives a query in a first format from a user device, wherein the first format is not executable in the database. The management agent parses the query to identify one or more commands in the query. The management agent translates the query into a modified query that is executable in the database. The management agent references one or more pre-loaded properties associated with the database. The management agent executes the translated query against the database. The management agent returns results of the execution.

Abstract: A system is described allowing a user to log into an API proxy by supplying login credentials and to have the API proxy log into the APIs of various web-based applications on behalf of the user by using the user's login credentials, without the user needing to separately log into each application. Calls made by the user to an application and application replies are routed through the API proxy. Further, the API proxy manages session expirations, e.g., by sending dummy calls to applications that exhibit idle expiration.
