You can also use filter:

// Discord.js v12 (latest version):
const count = guild.members.cache.filter(m =>
  // If the member has the role
  m.roles.cache.has('role id') &&
  // and the member is online
  m.presence.status === 'online'
).size

// Discord.js v11:
const count = guild.members.filter(m =>
  // If the member has the role
  m.roles.has('role id') &&
  // and the member is online
  m.presence.status === 'online'
).size

// Use count here:
client.user.setActivity('...')

To get a guild by its ID, use this:

// v12
const guild = client.guilds.cache.get('id')
// v11
const guild = client.guilds.get('id')
