Qapps

Hi guys,Can we create http/https checks in Netbrain for monitoring remote endpoints?Cheers

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

Hi! I was wondering if it would be possible to avoid using the typical Device Queue → For each Device → Command → Parse → DDT no-code sequence of NetBrain Qapps, and write it in code instead. I figured out how to loop through all the devices in the queue as the first two Nodes in the sequence would, but I’m a bit stuck on how to call the commands, as I’m not sure if there’s a built in API call I can use to do this or not. for row in $_device_queue.GetRows():    device = row['this']Getting raw input would be ideal. I don’t need help on the Parser bit or converting to a DDT as I’m quite familiar with regex and NetBrain’s Table API - so it’s really just the command part.My reason for the request, is that for a given device queue, I need to run a list of multiple different types of commands on each device. One command may be for getting the configuration, some are for CLI output, and some are for SNMP output, etc. I know about the loop-tables functionality, to be able to run multiple comma

Hello, Is it possible to use DrawDevice or DrawEndSystem Netbrain API to create an arbitrary ip address that will represent the internet or ISP BGP peer?

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.

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 do I access the built-in Device/Module/Interface Properties in Qapps such as:ManagementIP()Model()Vendor()SerialNumber()Instead of writing my own Parser(s), I would like to retrieve these values from the built-in Device Property Attributes. See page 207-213 for list of Device/Interface/Module Property attributes listed in PDF “How_to_Define_and_Use_Procedures.PDF” at Netbrain’s website: https://www.netbraintech.com/ftp/EE54G/How_to_Define_and_Use_Procedures.pdf As you can see below, I have a custom variable Column named mgmt_ip. The intent is to get the device’s management ip. I have tried different variations, including calling a function, but without success.Thanks in advance for your help! Best RegardsDavid

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

Hello, I would like to merge a table in a Canvas1 with a table from Canvas2 to get the complete Data in one new Table. Could you give me a hint?

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 

I am wondering if there is a way to access applications like qapp center without using the menu drop down? I understand there is the “pin the application” to the desktop option but is there another way? I am thinking of a url like what we might see with inventoryreport.  It can be loaded to a new tab but something like Qapp Center seems to only be in the drop down application section or pin. When we were using v8 we didn’t have this problem because the application search was in a different section.  We are using Netbrain V10.1.5.   Any ideas?

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

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! 

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 

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.

Do you have any device health check qapps? If not, how about this idea: check device hardware with various commands, e.g. Cisco's show module, show environmentshow moduleMod Ports Card Type                              Model              Serial No.--- ----- -------------------------------------- ------------------ -----------  4   48  48-port 10/100/1000 RJ45 EtherModule   WS-X6148A-GE-TX    x  5    5  Supervisor Engine 2T 10GE w/ CTS (Acti VS-SUP2T-10G       xMod MAC addresses                       Hw    Fw           Sw           Status--- ---------------------------------- ------ ------------ ------------ -------  4                                 f   4.2   8.4(1)       15.5(1)SY8   Ok  5                                 d   1.3   12.2(50r)SYS 15.5(1)SY8   MajFailMod  Sub-Module                  Model              Serial       Hw     Status ---- --------------------------- ------------------ ----------- ------- -------  5  Policy Feature Card 4       VS-F6K-PFC4        SAL16159W6L  1.

I have a runbook which has 2 Qapps and 1 Gapp, each of the Qapps generate Alerts based on the conditions and I can manually export the Alerts in csv format. Here, looking for a way to export the Alerts of Qapps/runbook using python or existing Netbrain APIs.

Greetings, I have many Qapps that each generate a CSV Export File. I need to combine, roll-up the CSV Export Files into a single CSV Export File. How can that be accomplished? Cheers

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.     

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

As there are two different types of Table shown under Qapp i.e DDT and GDT. What is the difference in between both of them?What is the significance of DDT and GDT?

Where can I download the supplied NetBrain Qapps?  I inadvertently deleted one of them.

How to trigger a Qapp to execute via an external script or an API when a certain condition met in network environment. 

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

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.
