Currently running a subscriber that is watching an action. The subscriber works and kicks off when the registered path is updated. If I make multiple changes to the registered path it will wait until it is done with the first notification then on to the next one. Is it possible for the subscriber to run with multiple threads.   The path the subscriber is registered takes devices names as input, then the subscriber runs some code on each device.   Thanks, ...

I am working on creating a service that will upgrade a certain model in our network. Ideally the service will first grab some yang data and then do the following below.   Is this a good use of pre/post services? Precheck copy over image if it doesn't exist and verify it, run some pre show commands. If I bundle all this together in just the service.create will it have consequences down the road if I remove the service? Or is this better suited for an Action and not a service in NSO?   @Service.pre_modification Pre-Modification code: Check router boot flash for all .bin files If more than one bin file delete all but current one Copy over new boot image to boot flash Verify Image Run pre check show commands, save to do diff on post check   @Service.create Set boot flash via template save running config reload router   @Service.post_modification Post Modification Code: wait for router to come back run post check show commands and do a diff with precheck  present diff of pre/post check to user or save to file system   Yang: module XE-Upgrade-IOS { namespace "http://example.com/XE-Upgrade-IOS"; prefix XE-Upgrade-IOS; import ietf-inet-types { prefix inet; } import tailf-common { prefix tailf; } import tailf-ncs { prefix ncs; } description "Service to upgrade ASR920 Routers to new image"; revision 2019-05-08 { description "Initial revision."; } list XE-Upgrade-IOS { description "upgrade IOS image on ASR920 XE"; uses ncs:service-data; ncs:servicepoint XE-Upgrade-IOS-servicepoint; key upgradeImage; leaf upgradeImage { tailf:info "Image to load/upgrade onto router"; type enumeration { enum '16.09.03'; enum '16.09.02'; } } leaf upgrade { tailf:info "Upgrade router if true, if false just preload image onto router"; type boolean; default false; } leaf deviceGroup { tailf:info "set to upgrade group, hidden"; type string; tailf:hidden "full"; default "920Upgrade"; } leaf deviceName { tailf:info "Choose device within preset device-group 920Upgrades"; type leafref { path "/ncs:devices/ncs:device-group[ncs:name=current()/../deviceGroup]/ncs:device-name"; } } } }   ...

I am working on a creating an action that returns some output for a certain show command. I can successfully run the command via the rest api but was wondering if it is possible to do the same via restconf and if their are any advantagaes to doing so.    Also what is the correct way to find a URI path for restconf?   REST api curl:   curl -X POST \ http://localhost:8080/api/running/NDOS:action/_operations/ShowCommands \ -H 'Authorization: Basic dAAAAAAAAAAAAAA==' \ -H 'Content-Type: application/vnd.yang.operation+xml' \ -H 'Postman-Token: AAAAAAAAAAAAAAAAAAAAAAA' \ -H 'cache-control: no-cache' \ -d '<input> <deviceName>CQ5LAB9K</deviceName> <showCMD>show l2vpn bridge-domain brief</showCMD> </input> ' Which outputs the results of the custom command and its parser.   <output xmlns='http://example.com/NDOS'> <result>{'CISCO_TAC': ['TEST_TAC'], 'EVPN_DHN': ['EVPN_2001'], 'Eng': ['LTE_LAB_1', 'LTE_LAB_2']}</result> </output> ...
