getdevicebyip on a qapp

Hi Team, i am trying to build a report via QAPP and want to populate the device name based on the IP.i’m using the inbuilt function “GetDevicesByIP” and that gives the output only when the variable type is string (not device) and is like below:<netbrain.common.models._datamodel.Device object at 0x000001F2803BFA60; name=XXXXXXX>] is there a better way to get just the XXXXX part on a QAPP. i;m aware the intents might handle this differently and im trying to have this implemented as a QAPP

Qapp using canvas1 to pull the P2P IP and canvas2 to run CLI cmd on P2P IP to parse ping output

Hello I am trying to build a Qapp that runs 2 CLI cmd, one to pull the P2P IPs on the link between 2 nodes in canvas 1 and then second to run the ping on the those P2P IP variables from canvas1. First parser in canvas1 below is getting all the local p2p IP and then I am using script to create p2p IP for neighboring node. I am able to get all the required variables (ipv4_peer and intf) here with no issues.sh ip int bri | e "down|Down" | e unassigned Second parser below should be using the canvas1 variables to get the ping results but it’s not showing me the intended results.ping $ipv4_peer source $intfMy end goal is running a DVT/Qapp on the map to show latency/ping delay on the links between 2 nodes. Not sure if there is an easier method available for this. Please advise.Thanks in advance.

Question with getInterfaceProperty

I am trying to understand how to use the getInterfaceProperty. I have a QAPP and wanted to input the description of an interface in one cells. The requirements are below. if I wanted to get the Descr for an interface but the interface is coming from the qapp how would the code go?$cell = getInterfaceProperty(‘Descr’,$_device,$intf,infs) ? I get no results and been trying to plug in the information with no change. Any suggestions?

How to retrieve One-IP List using python script?

Greetings, How can I get the One-IP List using python script? I couldn’t find a built-in function for it. I am not trying to use the API method. My ultimate goal is to retrieve the DeviceObject (DNS/Hostname and IP Address) of EndPoints connected to Access Switch Interfaces. I have the MAC Addresses of connected Endpoints, but there isn’t any built-in function to my knowledge to retrieve the DeviceObject by MAC Adddress. Using the ARP Table is not really feasible because I would first have to Find the Gateway Router, get the contents of the ARP Table and then do the mapping. The Interface Report Table from the Qapp inlcudes the fields DNSName and IPAddress, but unfortunately does not output it. Any help is appreciated! Best Regards, DaveDaMan

QApp scripting questions

Hi,I’m trying to understand the scripting environment a bit more for qApps and have a few questions. For a table driven canvas I can pass one of table column values as a parameter to a parser. Is it possible to pass any other types of variables to a parser, say from another script? If so, how do you make it so that the variable is in scope for the parser Is it possible to access those table columns from a table driven canvas in scripts attached to a following table? If so, what’s the syntax you need to use? What is the Variable Mapping option in the Run Options dialog used for?Many thanks in advance… Regards,Andy

QApp Python Script checking if GDT Table Variable is empty not working pythonic way?

Greetings, I just ran into an interesting problem: In Qapp, when I script a GDT Variable to check if a another GDT Table or Table Variable is empty, it does not work using pythonic way. How can I get to check if a Table Attribute (list) is empty or not without coming up with other creative solutions? Basically, the Attribute (list) or Table appears to never be empty despite containing no data. BID Table has _device, id and mac_limit attributes.GDT Table has attribute “note” that I use for scripting.When I check if BID Table (list) or BID.bid attribute (list) is empty is doesn’t return true for empty using pythonic way:#Check if BID.bid (list) is empty:if not $BID.bid: $cell = “PASSED: Bridge-Domains are not configured”. Although empty, it doesn’t match and continues to go through next else statement: The value returned is “None”. In the note, I run the following script:try: if $mpls_ldp is None: $cell = "NOT APPLICABLE: Device is not a PE Device." else: if not $BID

Qapp/Parser run second CLI command with variables/arguments from first CLI output

Hello, I am trying to create a Qapp that runs a CLI command with arguments/variables based on output of the first CLI command. Requirement: First CLI Command, get all Cisco IP BGP neighbors: show ip bgp neighbors one of the key variables, $bgp_neighbors, from the output contains the IP Address of the IP BGP Neighbor With the Cisco IP BGP Neighbors Table output, run a second CLI Command (Second Canvas) that runs a second CLI Command with a variable/argument $bgp_neighbors: show ip bgp neighbors $bgp_neighor advertised-route How can that be accomplished?Thanks in advance for your help!

Qapp get current row position of cell

Greetings, I need help with a Qapp on how rerieve the current Row Number of cell from a GDT/DDT. How is it possible using python in a custom variable column? I am creating a Cisco IP BGP Table from CLI Command “Show IP BGP”. Due to poor table output formatting, the Network and Next_Hop items overlap so that two rows are required for a single entry.As a result, in Qapp DDT or GDT the value for “network” (when too large and containing CIDR notation) is displayed in the “Next_Hop” column instead with not all other fields blank, while creating another row below containing all other columns values but a blank field in the Network Column.To fix that problem, I want to create a custom variable field that populates the correct Network Address by:finding current row position of cell retrieving the value of the Next_Hop field one row above current row positionAny help or pointers are appreciated. Best Regards, Dave

Use of NDP Table in a QApp

Has anyone had any success in using the device NDP table data within a QApp? I can see the NDP table data in the NetBrain GUI, but it says the data is unavailable in the database when I run the QApp.

how to draw device's L3 gateway using python script

I have been dabbling with the Qapp Python scripting lately and i want to build a qapp wherein the user can have multiple end device ips as input and have their L2 connected switch and L3 Gateways automatically drawn on the map using one-ip-table information. However, looks like the gateways cannot be resolved by one ip table that’s why it is not being drawn. Then i noticed when the end device is drawn, i am able to see the L3 neighbor by extending the plus sign. Is there a Qapp API or a combination of them that can see the L3 neighbor? Or is there a better way to achieve this? Thank you! import PyDataModeloutput = GetOneIpTableItem($Input1.IP,"","","")output has no entry for gw.

The historical data of the device and parser does not exist in the database

Greetings,I am new to NetBrain. I am currently learning how to write Parsers and Qapps. I am running into a problem with my Qapp. I am not getting the desired result when I run my Qapp against any current Baseline (Configuration) or Live Data. I am getting the following messages in the execution log: 1 3:59:15 PM: Start to run Qapp "Cisco_IOS_XE_Switch_Compliance_Check"2 3:59:22 PM: Run Qapp on 0 device group(s), 0 site(s), 0 path(s), xxx device(s)3 3:59:22 PM: Run Qapp on xxx qualified devices4 3:59:22 PM: The Process Id is 243123.5 3:59:23 PM: No data for "NET_DEVICE_1337 + Cisco_IOS_XE_Switch_Compliance_Check". The historical data of the device and parser does not exist in the database. What am I missing? Best Regards Dave

Upload Qapp result via SFTP

Hi,Recently we have developed some Qapps to do different things, like analysing BGP parameters in our routers and firewalls.We have found a problem when we’ve tried to upload the final CSV to a SFTP server. Netbrain allows me natively to upload the CSV to a SMB server, but I haven’t found the way to do it via SFTP.The only way to do it is via programmed plugin, but it keeps your SFTP user/pass exposed, which is not desirable.Has anyone resolved this issue? Thanks!!Juan

BGP advertised route qapp

I am looking to gather BGP advertised and received routes on a per BGP router basis. I’m sure it can be done via a QAPP/GAPP but need to investigate if anyone has created such before I reinvent the wheel. or if anyone know if such reporting is built into NetBrain.
