Visualization of flow trace operation across multiple sites

Abstract

Some embodiments provide a method for presenting a visualization of a data message flow within a logical network that is implemented across multiple sites. The method receives flow tracing data regarding the data message flow from a source endpoint in a first site to a second endpoint in a second site. The data message flow is processed according to logical forwarding elements (LFEs) implemented in at least the first and second sites. For each of the sites through which the data message flow passes, the method identifies the LFEs that process the data message flow in the site. The method presents a visualization for the data message flow. The visualization includes a separate section for each site through which the data message flow passes. Each section indicates at least a subset of the LFEs that process the data message flow in the corresponding site for the section.

         29 . The method of  claim 28 , wherein:
 a particular logical switch is implemented across at least two of the set of sites through which the data message flow passes; and   when the source endpoint and the second endpoint are both connected to the particular logical switch, the visualization includes a first GUI item for the particular logical switch in the first site, a second GUI item for a set of remote tunnel endpoints (RTEPs) used to forward the data message between the first and second sites, and a third GUI item for the particular logical switch in the second site.   
     
     
         30 . The method of  claim 26 , wherein the visualization comprises an indicator of latency between the first site and the second site, the indicator displayed between a first section for the first site and a second section for the second site. 
     
     
         31 . The method of  claim 26 , wherein the visualization identifies a set of LFEs with one or more alarms triggered by displaying GUI items for the set of LFEs using an indicator. 
     
     
         32 . The method of  claim 26 , wherein the visualization indicates a direction of the data message flow. 
     
     
         33 . The method of  claim 26 , wherein the separate sections in the visualization are displayed in an order starting with a first section for the first site and ending with a second section for the second site, with sections for each site through which the data message flow passes between the first and second sites displayed in order between the first and second sections. 
     
     
         34 . The method of  claim 33 , wherein the sections for each site through which the data message flow passes between the first and second sites are presented as collapsible within the visualization. 
     
     
         35 . The method of  claim 34 , wherein:
 within a particular section for a particular site, each LFE indicated as processing the data message flow within the particular site is presented as a separate GUI item; and   when the particular section is collapsed, the GUI items for the LFEs that process the data message flow at the particular site are not displayed.   
     
     
         36 . The method of  claim 33 , wherein when a number of sites through which the data message flow passes between the first and second sites is above a threshold, the sections for the sites through which the data message flow passes between the first and second sites are automatically presented as collapsed within the visualization. 
     
     
         37 . The method of  claim 34 , wherein each section that is collapsed within the visualization is expandable, wherein expanding a particular section corresponding to a particular site causes the visualization to display GUI items for at least a subset of the LFEs that process the data message flow in the particular site. 
     
     
         38 . A non-transitory machine-readable medium storing a program which when executed by at least one processing unit presents a visualization of a data message flow within a logical network that is implemented across first and second sites, the program comprising sets of instructions for:
