Struggling with Node.js API for Searching Profiles Across Multiple F5 Devices

Hello,

For Node.js have you considered parallel execution using async/await with Promise.all/Promise.allSettled ?  This will query all you BIG-IP devices concurrently which should help with keeping response time down.  You could also leverage axios-retry for retries depending upon the error codes.  On the BIG-IP side you will likely have to increase some of the restjavad settings refer here --> restjavad memory issues

Here is a sample code snippet to work off of:  

const axios = require('axios');
const retry = require('axios-retry');
const pLimit = require('p-limit');

retry(axios, { retries: 3, retryDelay: (retryCount) => retryCount * 1000 });

const mgmtIPs = ['10.0.0.1', '10.0.0.2', /* ... up to 40+ */];
const profileName = 'your-profile-name'; // From user input
const limit = pLimit(10); // Concurrency limit

async function queryDevice(ip) {
  try {
    // Create session token (POST /mgmt/shared/authn/login)
    const tokenRes = await axios.post(`https://${ip}/mgmt/shared/authn/login`, {
      username: 'admin', password: 'your-password' // Use env vars or secrets manager
    }, { timeout: 5000 });
    const token = tokenRes.data.token.token;

    // Query SSL or LTM profile (adjust endpoint: /mgmt/tm/ltm/profile/client-ssl or server-ssl for SSL, /mgmt/tm/ltm/profile for LTM)
    const profileRes = await axios.get(`https://${ip}/mgmt/tm/ltm/profile/client-ssl/${profileName}`, {
      headers: { 'X-F5-Auth-Token': token },
      timeout: 10000 // Custom timeout
    });
    return { ip, details: profileRes.data }; // Aggregate if found
  } catch (err) {
    console.error(`Error on ${ip}: ${err.message}`);
    return { ip, error: err.message }; // Don't throw; collect failures
  }
}

// In your API endpoint
async function searchProfiles(req, res) {
  const promises = mgmtIPs.map(ip => limit(() => queryDevice(ip)));
  const results = await Promise.allSettled(promises);
  const foundProfiles = results
    .filter(r => r.status === 'fulfilled' && !r.value.error)
    .map(r => r.value);
  
  res.json(foundProfiles); // Return aggregated list
}
