blockMatches on multiple patterns with the differentiator being a child line of output

I am trying to get data out of a Cisco DMVPN hub on the spokes via NHRP database.  Specifically the ARIN addresses and if the spoke has a firewall or other NAT. I was modelling off of this NQE question and it works...except for the 2nd pattern is not detecting the child line.The above question had a parent line that was always present if the new child was present and NHRP has the new child only if there is a NAT in the path while the parent line is always present. The line in question is the “(Claimed NBMA address: <IP address>)” line at the bottom of the 2nd example - it is indented 1 space from the line above ‘NBMA address’ which is always present. I tried both the NHRP data in the data model as well as a custom command ‘show ip nhrp’ with identical results.   //NHRP Database output//Command: show ip nhrp//10.100.12.5/32 via 10.100.12.5//   Tunnel1 created 1d18h, expire 01:56:31//   Type: dynamic, Flags: unique registered nhop//   NBMA address: 12.12.31.74//10.100.12.6/32 via 1

run nqe immediately after snapshot completes

is it possible to run NQEs immediately after a snapshot completes?  If Forward can baseline what NQEs are always run after a snapshot completes (possibly this data baseline is based upon a period of time such as 30 days or some admin defined time period).  Administrators can use this baseline data to flag those NQEs of priority to run immediately after the snapshot completes.  in this way, results from priority NQEs are immediately available (from cached results) for applications to use with minimal delay.

Three techniques for pattern matching text with patternMatch, patternMatches and blockMatches

This article explores NQE's robust pattern matching for extracting and parsing data, simplifying complex tasks with high-level, well-defined types for reporting and evaluation.Table of ContentsApproach 1: Leveraging the “or” pattern as described here Approach 1 Test  Approach 2 : Unifying multiple patterns Approach 2 Test Approach 3: Evaluation via token count Approach 3 Test Approach 1: Leveraging the “or” pattern as described here Using the following pattern`ntp server {"vrf" vrf:string server:string | server:string}`; We can accommodate various patterns for this command syntax by which the literal “vrf” and the VRF name maybe elided from the command. Instead of needing to create two separate patterns we can combine them into one expression.Looking closer at how we then extract the properties out of the data for vrf and server. The expression will append all properties to the left of the ‘|’ pipe operator to the data.left property and will append all properties to the right of the

Simplifying Compliance for Palo Alto Firewalls: Custom ChecksIntermediate

OverviewIn my recent work with Palo Alto firewalls, I noticed that keeping configurations compliant can get complex, especially when administrators need to modify default settings for certain applications. Small changes to session handling or TCP timeouts, while necessary for specific use cases, can introduce inconsistencies and potential compliance issues. I developed straightforward NQEs to create compliance checks that help us monitor and manage these configurations effectively. Key Benefits:Improved Visibility: The compliance checks I set up give us a clear view into any configuration deviations across firewalls, making it easy to spot unauthorized changes. Targeted Control: By creating separate compliance checks for different parameters, like session setup and timeouts, we can focus on what matters most in our environment. Unified Compliance Management: Even though Panorama handles many configurations, Forward Networks fills in the gaps by providing custom compliance checks, givin

Collecting custom command "show configuratation" within a a Cisco FPR running on FXOS

For reference - we recently were able to get Cisco Firepower ASA operating as FTD and FPRs on IOS FXOS, for the first time.  With that…. Since none of the default commands produce any data in the state files, we are trying to use custom commands.  Right now, when performing a show run, it comes back with 25 lines of configs, but then stops at --More--, which is when a user via cli would would push a button.  We have lots of other devices running custom commands that do not do this, so why is it happening with FXOS and how can we work around it? Also, the FTD devices reporting all state files properly, its just the FPRs that are having issues.

Combining NQE queries into a single check

Suppose you are using NQE queries to validate that your networking devices follow certain configuration benchmarks. You have an individual query for each benchmark, but you would also like a summary query that shows how each device in the network performs against every check. Here is how you can combine them.Below are two separate NQE queries that validate that the password policies on Cisco ASA devices require a minimum number of numbers and a minimum number of special characters, respectively.In each query, we define a function using the export command that takes in a Device as a parameter. export minNumber(device: Device) Then we call that function later in the same query with minNumber(device). This allows the query to be run on its own or part of another query.We save each file as min-numeric and min-special.pattern = ```password-policy minimum-numeric {minNum:number}```;checkPattern(config) = (max(blockMatches(config, pattern)))?.data?.minNum >= 1;export minNumber(device: Devi

Sample NQE for Golden Config Compliance and Remediation

I recently have done alot of work on building Golden Config and using NQE queries to find Actual Config on devices and compare to Golden Config and then building the remediation config so actual config will match Golden Config. I did this so Operations engineers can utilize the remediation config to implement on device either manually or through an Ansible playbook that utilizes the NQE Query and then build a workspace on devices being worked on to verify that Golden Config was implemented correctly on device(s). Below is a sample Query for a small section of config to ensure NTP configuration is correct on a Juniper device: goldenConfig_ntp_list =  ["set system ntp server 10.10.10.10",   "set system time-zone UTC"  ];foreach device in network.deviceswhere device.platform.os == OS.JUNOSlet outputs = device.outputsforeach command in outputs.commands  where command.commandText == "show configuration | display set"  let text = parseConfigBlocks(OS.JUNOS, command.response)let configList =

Unlocking New Potential: Fixed-Length Encoding and NQE List Operations

Introduction Hello Community!  I wanted to share something I’ve been working on that may be helpful to you. It's a query designed to manipulate list arrays by transforming list elements into fixed-length strings, which then lets us easily join, split, or pop elements.  NQE built-in functions provide list iteration and for the most part, this satisfies data model iteration for our queries. The approach presented here extends NQE list operation abilities to manipulate lists or extract specific values when required.To accomplish this  we can apply a well known process called fixed-length string encoding which involves standardizing the length of each item in a list. By transforming variable-length strings into uniform sizes, we can “index” each item making if possible  to perform operations like joining, splitting, and extracting elements. It opens up new possibilities for customizing functions beyond the basics of list iteration and hopefully, it will serve as a helpful tool when you nee
