+Top 3 on CPU (via htop): 
+![htop cpu](../screenshots/Screenshot1.png)
+As expected, the instant replay app, window manager and screenshot manager are the top 3
+
+Top 3 on RAM% (via top):
+![top ram%](../screenshots/Screenshot2.png)
+Browser, Telegram and Desktop session. No surprises.
+
+Top 3 on IO R/W (via htop):

+Mounted drive, systemd-journald and a music player. No surprises again.

+ Overall the best optimization would be to uninstall chromiun from my pc, unfortunately my mouse configuration app and Discord both require it. Jokes aside probably nothing to be done of significance.

+ ## Task 2
+I decided to use my beloved *g.co* website.
+
+Checking for 200 response from g.co
+![api check](../screenshots/Screenshot4.png)
+Config:
+![api check config](../screenshots/Screenshot6.png)
+
+Checking for loading Google's logo
+![logo check](../screenshots/Screenshot5.png)
+Playwright config:
+```js
+const { expect, test } = require('@playwright/test')
+
+// Configure the Playwright Test timeout to 210 seconds,
+// ensuring that longer tests conclude before Checkly's browser check timeout of 240 seconds.
+test.setTimeout(210000)
+
+// Set the action timeout to 10 seconds to quickly identify failing actions.
+test.use({ actionTimeout: 10000 })
+
+test('wait for an element to become visible', async ({ page }) => {
+  await page.goto(process.env.ENVIRONMENT_URL || 'https://www.g.co')
+
+  // Locate the logo and check if it's visible
+  const companyLogo = page.getByAltText("Google")
+  await expect(companyLogo).toBeVisible()
+
+  // Take a screenshot of the current page
+  await page.screenshot({ path: 'screenshot.jpg' })
+})
+```
+
+Alerts config:
+![alerts config](../screenshots/Screenshot7.png)
+
+I used simple checks for a simple website (definetly slacking off).
+Monitoring is crucial for modern web service model, since downtime = less money. If a website is down, its owner must be notified ASAP to get it back up.
